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.
