Heads are rolling in USC's athletic department over the college admissions scandal and university fundraising -- a key part of Lori Loughlin and Mossimo Giannulli's defense.
The university just fired 3 officials -- CFO Steve Lopes, senior associate athletic director, Ron Orr and associate athletic director Scott Jacobson. USC hasn't said why they were canned, but we've confirmed all 3 were heavily involved in fundraising efforts for Trojan athletics.
TMZ broke the story ... Mossimo wrote a check for $50k, payable directly to USC.
