On the second day of the first “Varsity Blues” trial, jurors on Monday heard phone recordings between the scheme’s ringleader, Rick Singer, and Gordon Caplan, the former co-chairman of Willkie Farr & Gallagher, who admitted to paying a bribe to rig his daughter’s ACT score.

While Caplan is among the dozens of parents charged in the college admissions scheme who have pleaded guilty, two wealthy parents—former hotel and casino executive Gamal Abdelaziz and private equity firm founder John Wilson—are fighting accusations that they paid hundreds of thousands of dollars in bribes to get their children into prestigious schools as athletic recruits using fake profiles. Both men have pleaded not guilty.
