One of the claimants in the Trump University case—herself a Florida lawyer—has asked a federal appeals court to unravel the $25 million agreement that settled the matter shortly after the election of President Donald Trump—and she's brought in noted appellate attorney Deepak Gupta to do it.

Gupta, who is already spearheading a case against Trump brought under the emoluments clauses of the Constitution, adds legal firepower to the claims of Sherri Simpson, who unsuccessfully objected to the Trump University settlement in March.

On Monday, she petitioned the U.S. Court of Appeals for the Ninth Circuit to reverse U.S. District Judge Gonzalo Curiel's approval of the settlement.
