Los Angeles – Prosecutors are withholding evidence that would show Lori Loughlin and her husband, Mossimo Giannulli, believed the 500,000 dollars they paid to a college admissions consultant’s charity was a legitimate donation, not bribes that would ensure their daughters were admitted to the University of Southern California as rowers, the couple’s attorneys wrote in a court filing.

The couple’s legal team, led by former Enron prosecutor Sean Berkowitz, is demanding the government turn over FBI reports, known as 302s, that memorialized agents’ interviews with the consultant at the center of the scheme, William “Rick” Singer.

Those reports would show where Singer told his clients their six-figure payments would end up, Berkowitz wrote. In the case of Loughlin and Giannulli, who have been charged with conspiracy to commit fraud, money laundering and bribery, the couple thought their money “would go to USC itself – for legitimate, university-approved purposes – or to other legitimate charitable causes,” their lawyers wrote.

Prosecutors from the U.S. attorney’s office in Boston have so far refused to disclose the FBI reports, Berkowitz wrote. They have provided only a summary of Singer’s discussion of his dealings with Loughlin and Giannulli, he said.

The summary is appended to Berkowitz’s filing. Singer explained to the couple that to have their daughters admitted to USC as recruited coxswains, they “would need to write a 50,000-dollar check to Donna Heinel at USC and pay an additional 200,000 dollars through the KWF,” the summary says. KWF is short for Singer’s charity, the Key Worldwide Foundation.
