Before ELROD, DUNCAN, and WILSON, Circuit Judges. JENNIFER WALKER ELROD, Circuit Judge: Appellant Adam Cooper pleaded guilty to one count of possession with intent to distribute methamphetamine and one count of possession of a firearm in furtherance of a drug-trafficking crime. On appeal, Cooper contends that the facts do not support his guilt of the firearm offense. Because there is a sufficient factual basis to show Cooper possessed a firearm in furtherance of a drug-trafficking crime, we AFFIRM. Nevertheless, because the court’s judgment erroneously indicates that Cooper pleaded guilty to the second superseding indictment—when in fact he pleaded guilty to the superseding indictment—we REMAND for correction of the judgment under Federal Rule of Criminal Procedure 36. I. Cooper was driving a grey Chevrolet Impala down 42nd Street in Odessa, Texas with Tracy Marriott in the passenger seat when the Odessa Police Narcotics Unit stopped the vehicle for failing to signal a turn. Both Cooper and Marriott consented to a search. The search revealed drug paraphernalia, marijuana, methamphetamine, and a backpack. The backpack was “on the floorboard of the front passenger seat,” where Marriott was sitting, and it contained drug paraphernalia, baggies, and a Smith and Wesson M&P, 9mm pistol. Marriott, after being advised of his Miranda rights, said “that the backpack was his and that he had traded an AR-15 rifle for a pistol the day before.” Cooper pleaded guilty to two counts arising from this incident: (i) possession with intent to distribute fifty grams or more of actual methamphetamine and (ii) possession of a firearm in furtherance of a drug- trafficking crime in violation of 18 U.S.C. § 924(c). With Cooper’s consent, Magistrate Judge Ronald Griffin received Cooper’s plea and conducted the Rule 11 plea colloquy. Fed. R. Crim. P. 11(b)(1); The magistrate judge read the charges to Cooper and asked Cooper if he understood the charges. Cooper replied “Yes, I do your Honor.” The government read into the record the factual basis for the charges, which included the facts described above, as well as the statement, “The defendant admits and agrees that . . . he possessed a firearm in furtherance of” the drug-trafficking offense. Cooper affirmed that “the factual summary accurately state[d] what [he] did in this case.” Cooper then pleaded guilty, and the district court accepted Cooper’s plea “on Counts ONE AND TWO of the SUPERSEDING INDICTMENT” At sentencing, Cooper continued to accept responsibility, but he briefly contested the fact that he knew about the firearm, claiming he knew only that Marriott had a backpack and not that there was a gun. Reading from the probation officer’s pre-sentence report, the judge incorrectly stated that Cooper, “after being warned of [his] Miranda warnings, . . . admitted the backpack was [his] and the firearm belonged to [him].” In fact, it was Marriott, not Cooper, who made this admission. Cooper noted this to the court saying, “That’s not from me. That’s not the probation talking about me on there. I’m sorry but— . . . It wasn’t in my backpack or in any of mine.” The judge then replied “Well regardless— . . . you did plead guilty to both of these, right? Because you understand the law, it makes you guilty of them, right?” Cooper responded, “Yes, Your Honor.” The district court subsequently entered judgment on what it described as Cooper’s guilty plea “to Count(s) 1 and 2 of the Second Superseding Indictment.” Cooper timely filed notice of appeal, and this court appointed appellate counsel. Counsel then moved to withdraw by filing an Anders brief asserting that Cooper’s appeal was without merit. See Anders v. California, 386 U.S. 738, 744 (1967). Because this case could present an issue of aiding- and-abetting liability for a § 924(c) offense, we carried that motion with the case and ordered counsel to file either a supplemental Anders brief addressing Rosemond v. United States, 572 U.S. 65 (2014) or “a brief on the merits addressing any nonfrivolous issues that counsel deems appropriate.” Cooper filed a brief on the merits arguing that the district court “failed to fully investigate whether the factual basis supported” Cooper’s guilty plea to the firearm-possession count, as required by Federal Rule of Criminal Procedure 11(b). The core of Cooper’s argument is that there is an insufficient factual basis to conclude that Cooper had the mens rea required by United States v. Smith to be guilty of possessing a firearm in furtherance of a drug-trafficking crime. 878 F.3d 498, 501 (5th Cir. 2017). Cooper does not address or cite to Rosemond. Conversely, the government contends that the facts are sufficient to conclude that Cooper had the advance knowledge required by Rosemond, 572 U.S at 78, to be guilty of aiding and abetting a § 924(c) offense. The government further contends that the facts are sufficient to show that the possession of the firearm was in furtherance of a drug-trafficking crime. II. There is a conflict in the record as to whether Cooper pleaded guilty to the superseding indictment or the second superseding indictment. The government notes this conflict in its brief on appeal, but neither the government nor Cooper discuss the significance of the conflict. At Cooper’s plea hearing, only the superseding indictment was pending against Cooper. The government explained that it intended to file a second superseding indictment in order to add a conspiracy charge against Cooper’s codefendant. It intended to then move to dismiss the second superseding indictment as to Cooper. The district court accepted Cooper’s guilty plea to the superseding indictment. At sentencing, however, the government told the district court that Cooper had pleaded guilty to the second superseding indictment. The government then moved to dismiss the indictment, the superseding indictment, and the conspiracy charge in the second superseding indictment; the district court granted the motion. After the hearing, the district court purported to enter judgment on the second superseding indictment. Counts one and two of the superseding indictment are nearly identical to counts one and two of the second superseding indictment. Both indictments charge one count of possession with intent to distribute 50 grams or more of actual methamphetamine and one count of possession of a firearm in furtherance of a drug-trafficking offense. The indictments differ, however, in one respect. Count 2 of the superseding indictment alleges that Cooper and Marriott “aided and abetted by each other” possessed a firearm in furtherance of a drug-trafficking offense. Count 2 of the second superseding indictment, however, excludes the words “aided and abetted by each other.”[1] Both indictments cite to 18 U.S.C. § 2, the federal aiding-and- abetting statute. Because aiding and abetting is a theory of liability, rather than a separate offense, the exclusion of “aided and abetted by each other” does not constitute a change in the offense charged. See 18 U.S.C. § 2; United States v. Masson, 582 F.2d 961, 963 (5th Cir. 1978). There is no meaningful difference, therefore, between the indictments. Nevertheless, a problem still remains because the district court dismissed the superseding indictment, to which Cooper pleaded guilty. As noted above, neither party briefed the court on a solution to this problem. The proper remedy is to remand this case for correction of the judgment under Federal Rule of Criminal Procedure 36. Rule 36 allows the district court to “at any time correct a clerical error in a judgment, order, or other part of the record, or correct an error in the record arising from oversight or omission.” Fed. R. Crim. P. 36. In several unpublished cases, we have previously used Rule 36 to correct errors in the judgment relating to dismissed indictments and to the offense underlying a plea. See United States v. McCoy, 819 F. App’x 262, 262 (5th Cir. 2020) (remanding to correct the judgment to reflect the crime to which the defendant pleaded guilty); United States v. Stark-Fitts, 802 F. App’x 845, 845 (5th Cir. 2020) (remanding to correct the amended judgment by adding a checkmark to clarify that the indictment, first superseding indictment, and second superseding indictment were dismissed); United States v. Ulloa-Osorio, 637 F. App’x 142, 143 (5th Cir. 2016) (remanding to correct the judgment by adding the dismissal of count two, which was omitted). There is, of course, a limit to what Rule 36 can do. In United States v. Ramirez-Gonzalez, we held that the purpose of Rule 36 is “only to correct mindless and mechanistic mistakes. Where the record makes it clear that an issue was actually litigated and decided but was incorrectly recorded in or inadvertently omitted from the judgment, the district court can correct the judgment under” Rule 36. 840 F.3d 240, 247 (5th Cir. 2016) (internal quotation marks and citations omitted). Rule 36 does not cover deliberate drafting choices, such as the deliberate wording of a pre-sentence report. Id. Here, the error in the judgment arose from the oversight of the parties and the district court at the sentencing hearing when the government incorrectly represented that Cooper had pleaded guilty to the second superseding indictment. The transcript of the plea hearing makes clear that Cooper pleaded guilty to the superseding indictment and that the parties intended to dismiss the second superseding indictment against Cooper; i.e., this issue was actually litigated. Moreover, there is no meaningful difference between counts one and two of the superseding indictment and counts one and two of the second superseding indictment. This error falls within both the literal reach of Rule 36 and the limitation imposed by Ramirez-Gonzalez. Therefore, we remand for correction of the judgment under Rule 36. III. We now turn to the merits of Cooper’s appeal. Cooper makes two interrelated arguments on appeal: first, that the district court should have inquired as to whether there was a sufficient factual basis to support Cooper’s guilty plea to count 2, the firearm count; second, that the factual basis is, in fact, insufficient to show that his possession of the firearm was in furtherance of the drug-trafficking offense because he did not know that the firearm was in the car. Cooper’s first argument that the district court should have inquired further is meritless. Cooper correctly states that the district court has a “duty to compare the factual basis to the elements of the offense to determine if the factual basis supports conviction before accepting the plea.” See Fed. R. Crim. P. 11(b)(3); United States v. Adams, 961 F.2d 505, 511 (5th Cir. 1992). The district court, however, satisfied this duty through the Rule 11 colloquy conducted by the magistrate judge at the plea hearing. United States v. Bolivar-Munoz, 313 F.3d 253, 256–57 (5th Cir. 2002) (explaining that a district judge’s delegation of authority to a magistrate judge is proper when the assigned duty is “‘subject to meaningful review’ by the district judge”). Cooper properly consented to the magistrate judge conducting the colloquy; the magistrate judge explored the factual basis for count two by comparing the available facts to the elements of the offense alleged; and the district judge reviewed and accepted Cooper’s guilty plea.[2] Cooper’s second argument that the factual basis was insufficient also fails. Because Cooper did not challenge the sufficiency of the factual basis for his guilty plea in the district court, this court reviews for plain error. United States v. Ortiz, 927 F.3d 868, 872 (5th Cir. 2019). To show plain error, Cooper must show a forfeited error that is clear or obvious and that affects his substantial rights. Puckett v. United States, 556 U.S. 129, 135 (2009). We may, in our discretion, correct the error if it seriously affects the fairness, integrity, or public reputation of judicial proceedings. Id. To determine if the facts support Cooper’s guilty plea to count 2, we may consult all relevant materials in the record. Adams, 961 F.2d at 508. This includes the indictment itself, evidence available at the plea hearing, evidence “adduced after the acceptance of a guilty plea but before or at sentencing,” the pre-sentencing report, et cetera. United States v. Hildenbrand, 527 F.3d 466, 475 (5th Cir. 2008); see also United States v. Trejo, 610 F.3d 308, 313 (5th Cir. 2010). According to Cooper, his possession of the firearm could not have been “in furtherance” of the drug-trafficking offense in count 1 because he did not have any “prior knowledge of [the firearm] before Marriott entered the vehicle.” Possession of a firearm is “in furtherance” of a drug-trafficking offense if the possession furthers, advances, or helps forward that offense.[3] United States v. Ceballos-Torres, 218 F.3d 409, 412 (5th Cir. 2000). This possession must be “knowing possession with a nexus linking the defendant and the firearm to the [drug-trafficking] offense.” Smith, 878 F.3d at 502. Cooper points to the fact that the firearm was found in Marriott’s closed backpack on the passenger side of the car as evidence that he did not know about the firearm. He does not, however, address the fact that the backpack also contained drug paraphernalia and plastic baggies commonly used in the distribution process. While Cooper claims he did not know about the contents of the backpack, he knew about the backpack itself, and he certainly knew about the methamphetamine he was transporting. Furthermore, firearms are common “tools of the trade” of drug trafficking. United States v. Zapata-Lara, 615 F.3d 388, 390 (5th Cir. 2010) (quoting United States v. Aguilera-Zapata, 901 F.2d 1209, 1215 (5th Cir. 1990)). Together, this evidence is more than sufficient to support the conclusion that Cooper knew about the firearm and that the possession was in furtherance of the methamphetamine trafficking charged in count 1. Ceballos-Torres, 218 F.3d at 412; see also Zapata-Lara, 615 F.3d at 390 (discussing when a court may infer knowledge based on the facts of a drug-trafficking offense). Cooper does not show any plain error. Finally, Cooper forfeited any argument he might have under Rosemond by not briefing the issue. See Coleman v. United States, 912 F.3d 824, 836 n.14 (5th Cir. 2019) (reaffirming that failure to adequately brief an issue on appeal constitutes forfeiture of that argument); see also United States v. Scroggins, 599 F.3d 433, 449 (5th Cir. 2010) (distinguishing forfeiture from voluntary waiver of an argument). Our March 30 order instructed Cooper’s counsel to either file a supplemental Anders brief addressing Rosemond or “a brief on the merits addressing any nonfrivolous issues that counsel deems appropriate.” Consistent with that order, Cooper’s counsel chose the latter route, filing a brief on the merits which does not address Rosemond. In Rosemond, the Supreme Court addressed the issue of the mens rea required to aid and abet the possession of a firearm in furtherance of a drug-trafficking offense in violation of 18 U.S.C. §§ 2 and 924(c). 572 U.S. at 75. Cooper does not cite to Rosemond, and he discusses instead the distinct mens rea issue of the knowledge required to directly commit—rather than aid and abet—a § 924(c) offense.[4] See Smith, 878 F.3d at 502; Ceballos-Torres, 218 F.3d at 412–15. Assuming arguendo that Cooper did not forfeit a Rosemond argument, any Rosemond challenge would fail on this record. In Rosemond the Supreme Court explained that § 924(c) is a “combination crime” because it requires not just the possession of a firearm but also the commission a drug-trafficking crime. 572 U.S. at 71, 75. To show that the defendant intended to facilitate the commission of a § 924(c) offense—the intent requirement for aiding and abetting—the government must show that the defendant intended the commission of both aspects of § 924(c). Id. at 72, 76. This means that the government must show, at least, that the defendant had advance knowledge of the presence of a firearm. Id. at 78. The record contains Cooper’s own admission that he possessed the firearm: [THE PROSECUTOR:] The defendant admits and agrees that he possessed with intent to distribute more than 50 grams of actual methamphetamine, and that he possessed a firearm in furtherance of that offense. THE COURT: Mr. Cooper, do you agree with the factual summary as read by the government’s attorney? THE DEFENDANT: Yes, your Honor. . . . . THE COURT: Okay. Mr. Cooper, is there anything that you disagree with in that factual summary that you would like to change, make objections to? THE DEFENDANT: No, your Honor. THE COURT: All right. Does the factual summary accurately state what you did in this case? THE DEFENDANT: Yes, your Honor. It is well settled in this Circuit that an admission during a plea colloquy can support a guilty plea. See United States v. Chandler, 125 F.3d 892, 898 (5th Cir. 1997) (determining that defendant’s admissions supported conviction). The record also contains circumstantial evidence supporting Cooper’s advance knowledge, such as the presence of the firearm in Cooper’s car and the proximity of the gun to paraphernalia of drug distribution. The district court did not plainly err in accepting Cooper’s guilty plea. * * * For the foregoing reasons, we AFFIRM the judgment of the district court but REMAND the case for correction of the judgment under Rule 36 to reflect that Cooper pleaded guilty to the superseding indictment.
