Melton, Chief Justice. Renita Collins was tried for murder along with co-defendant Michael Stallworth.[1] Collins appeals her convictions for murder and possession of a firearm while in commission of a felony in connection with the shooting death of Keith Jacobs.[2] Collins contends that she was denied a fair trial due to juror misconduct, the trial court abused its discretion by not allowing her to subpoena juror testimony to show that misconduct had occurred, and the trial court abused its discretion when it failed to excuse a prospective juror for cause. For the reasons set forth below, we affirm. 1. As was also the case in Stallworth, supra, 304 Ga. at 333334 (1), viewed in the light most favorable to the verdicts, the evidence presented at trial shows that, on the evening of March 2, 2011, Jacobs and his fiancee, Cassandra Horns, were sitting on the front porch of his Fulton County home when Collins walked up to the edge of the yard. Collins began yelling at Jacobs about Jacobs’s dog and threatened to shoot the dog the next time it barked at her. Jacobs and Collins got into a heated argument. Collins left, saying that she would return, and walked to her house, which was nearby. Jacobs’s brother, Michael Walker, came out of Jacobs’s house to try to calm Jacobs down. Moments later, Collins returned to Jacobs’s house with Stallworth. A new argument ensued. Horns and Walker both left the porch and went in the house. Shortly thereafter, they heard gunshots. Walker ran outside to find Jacobs fatally wounded from a gunshot to the back of the head. Multiple witnesses testified that Collins argued with Jacobs, walked to Collins’s home, returned to Jacobs’s house with Stallworth, continued an argument with Jacobs, and then multiple gunshots were fired. Several witnesses saw people matching Collins and Stallworth’s descriptions fleeing from the direction of Jacobs’s house. One witness saw Collins with a gun just before the shooting, and another witness saw a person matching Stallworth’s description with a gun immediately after the shooting. Two witnesses identified Stallworth from a photographic lineup, and one witness identified Collins from a photographic lineup. Although Collins does not challenge the sufficiency of the evidence supporting her convictions, as is our customary practice in murder cases, we have reviewed the record and conclude that the evidence presented at trial was sufficient for the jury to find Collins guilty beyond a reasonable doubt of the crimes for which she was convicted. Jackson v. Virginia, 443 U. S. 307 (III) (B) (99 SCt 2781, 61 LE2d 560) (1979). See also Stallworth, supra, 304 Ga. at 334 (1). 2. Collins asserts that she was denied a fair trial due to juror misconduct. Specifically, she contends that several jurors, in a post- trial conversation with Stallworth’s defense counsel, questioned why Stallworth had not testified, and that these questions about Stallworth show that the jurors also held Collins’s failure to testify against her, thereby raising a presumption of prejudice against her. We disagree. The record shows that, at the conclusion of Collins and Stallworth’s trial, the trial court instructed the jury regarding the defendants’ presumptions of innocence and to not consider either defendant’s election not to testify when determining guilt or innocence. Immediately following the publishing of the guilty verdicts, counsel for the parties met with the jurors. A subset of approximately four jurors asked Stallworth’s trial counsel why Stallworth had not testified. Stallworth’s counsel responded that Stallworth had the constitutional right not to testify. When a juror asked again why Stallworth had not testified, his counsel did not answer and redirected the conversation. At the hearing on Collins’s motion for new trial, Stallworth’s counsel testified that none of the jurors indicated they had drawn a negative inference from Stallworth’s failure to testify. The trial court’s staff attorney, who was in attendance at the post-trial meeting, testified that the jurors’ questions “seemed to go a little bit beyond curiosity” and that he “got the impression that they were considering [it] in their deliberations.” Collins argues that, although the trial court properly instructed the jury, the jurors engaged in misconduct by not following those instructions. She relies on the attorneys’ testimony about their concerns with the jurors’ post-trial questions to establish this misconduct. She further argues that the trial court erred by not allowing her to subpoena jurors to help her meet her burden of showing juror misconduct. However, because neither the attorneys’ impressions about what the jurors may have considered during their deliberations nor the jurors’ own testimony about their deliberations is admissible evidence, Collins’s claim of juror misconduct fails. Longstanding common-law principles prohibit using juror statements or testimony to impeach their own verdict. See Tanner v. United States, 483 U.S. 107, 121 (II) (1987). This prohibition is embodied within Federal Rule of Evidence 606, from which Georgia adopted its current rule regarding the admissibility of juror testimony. See United States v. Brown, 934 F3d 1278, 1302 (III) (B) (3). See also Beck v. State, 305 Ga. 383, 385 (2) (825 SE2d 184) (2019). OCGA § 24-6-606 states, in relevant part: Upon an inquiry into the validity of a verdict or indictment, a juror shall not testify by affidavit or otherwise nor shall a juror’s statements be received in evidence as to any matter or statement occurring during the course of the jury’s deliberations or to the effect of anything upon the jury deliberations or any other juror’s mind or emotions as influencing the juror to assent to or dissent from the verdict or indictment or concerning the juror’s mental processes in connection therewith; provided, however, that a juror may testify on the question of whether extraneous prejudicial information was improperly brought to the juror’s attention, whether any outside influence was improperly brought to bear upon any juror, or whether there was a mistake in entering the verdict onto the verdict form. OCGA § 24-6-606 (b) (“Rule 606 (b)”).[3] As both the attorney testimony regarding juror statements made during the post-trial conversation, and the juror testimony Collins seeks in order to bolster her claim, fall within Rule 606 (b)’s prohibition against using juror testimony or statements to impeach a verdict, Collins has failed to produce admissible evidence of juror misconduct. Collins contends that the jury’s alleged consideration of her choice not to testify, by itself, constitutes extraneous prejudicial information and, therefore, the jurors’ testimony on the issue falls within Rule 606 (b)’s exceptions. That is incorrect. Georgia’s Rule 606 (b) is borrowed from Federal Rule of Evidence 606 and, as such, when interpreting its meaning, we are guided by the decisions of federal appeals courts and particularly the Eleventh Circuit. Beck, supra, 305 Ga. at 385-386. The Eleventh Circuit has stated that Rule 606 (b) “imposes a nearly categorical bar on juror testimony.” (Citation omitted.) United States v. Foster, 878 F3d 1297, 1309 (III) (D) (11th Cir. 2018). When interpreting Rule 606 (b)’s exception regarding extraneous prejudicial information, the Eleventh Circuit distinguishes between “external” information, which comes from a source outside the jury, and “internal” matters, which include statements made during deliberations. Id. at 1310 (III) (D). All federal appellate courts to have considered whether jurors’ discussions regarding a defendant’s decision not to testify fall within Rule 606 (b)’s exception for extraneous prejudicial information have consistently held that such discussions do not, by themselves, constitute “external” information about which jurors can testify. See United States v. Friedland, 660 F2d 919, 927-928 (3d Cir. 1981) (inquiry into whether jurors had considered and discussed defendant’s failure to testify fell “squarely within the prohibition of Rule 606 (b),” because such discussion did not stem from extraneous prejudicial information or an outside influence); United States v. Martinez-Moncivais, 14 F3d 1030, 1036-1037 (II) (B) (5th Cir. 1994) (jurors’ post-trial statements that an innocent defendant would have testified in his own defense did not fall within the exceptions to the rule prohibiting admission of juror testimony to impeach a verdict); United States v. Kelley, 461 F3d 817, 831-832 (II) (D) (6th Cir. 2006) (because defendant’s failure to testify was simply “part of the trial” and jurors did not learn of the failure to testify through improper channels, such information does not fall within Rule 606 (b)’s exceptions); United States v. Tran, 122 F3d 670, 673 (II) (8th Cir. 1997) (defendant’s failure to testify did not constitute extraneous information because jurors learned of it as a result of their presence at trial rather than from events or persons outside the courtroom); United States v. Rutherford, 371 F3d 634, 640 (II) (9th Cir. 2004) (where information does not come from outside source, juror testimony about discussion of a defendant’s failure to testify during deliberations is inadmissible); United States v. Voigt, 877 F2d 1465, 1469 (10th Cir. 1989) (juror statement that defendant was found guilty because of her failure to testify was not extraneous or outside information, rather was the type of internal deliberation about which Rule 606 (b) prohibits jurors from testifying). Thus, the trial court did not abuse its discretion when it ruled that the juror testimony sought by Collins was inadmissible. In addition, as Collins has not presented any other admissible evidence under Rule 606 (b) that supports her claim of juror misconduct, her claim fails. 3. Next, Collins contends that the trial court abused its discretion by failing to strike Juror 18 for cause.[4] The record shows that during voir dire, Juror 18 was asked if his personal life experiences would affect his ability to be fair and impartial in this case. He responded, “I think [they] might.” He was asked if he could judge the evidence in this case and come to a verdict that speaks the truth, and he responded, “Yes.” When asked if the fact that the defendants had been indicted tilted the scale against them, he responded, “A little bit, yeah.” He was also asked if it was fair to say that, due to the existence of the indictment and his “conservative leaning,” he was not fair and impartial, and he responded, “That’s a fair statement.” Juror 18 was then asked if he could follow the instructions from the Court and listen to the evidence and reach a verdict that speaks the truth from what he learned in the courtroom. He responded, “I believe I could — I don’t know if I could do a clean slate, but if I listened to the facts — and both sides’ arguments, I think I could.” “Whether to strike a juror for cause lies within the sound discretion of the trial judge, and the trial court’s exercise of that discretion will not be set aside absent a manifest abuse of discretion.” (Citations omitted.) Poole v. State, 291 Ga. 848, 851 (3) (734 SE2d 1) (2012). For a juror to be excused for cause, it must be shown that he or she holds an opinion of the guilt or innocence of the defendant that is so fixed and definite that the juror will be unable to set the opinion aside and decide the case based upon the evidence or the court’s charge upon the evidence. A prospective juror’s doubt as to his or her own impartiality does not demand as a matter of law that he or she be excused for cause. Nor is excusal required when a potential juror expresses reservations about his or her ability to put aside personal experiences. A conclusion on an issue of bias is based on findings of demeanor and credibility which are peculiarly in the trial court’s province, and those findings are to be given deference. (Citation and punctuation omitted.) Brockman v. State, 292 Ga. 707, 721 (9) (739 SE2d 332) (2013). In light of these principles and the record before us, we conclude that, although Juror 18 expressed some initial doubts, the trial court did not abuse its discretion in finding that the juror had not expressed an opinion of guilt or innocence that was so fixed that he would be unable to decide the case based on the evidence presented at trial and the charge of the trial court. See id. Judgment affirmed. All the Justices concur.
