University of Southern California students who have been linked with the college-admissions scandal have been blocked from registering for classes or getting transcripts, the school has announced. The daughters of actress Lori Loughlin, who was charged in the alleged scam, study at USC. Tweeting late Monday, the school announced: “USC has placed holds on the accounts of students who may be associated with the alleged admissions scheme; this prevents the students from registering for classes or acquiring transcripts while their cases are under review.” The scam is alleged to have helped parents buy their kids way into colleges by getting them admitted to elite universities as recruited athletes or helping them cheat on entrance exams. Federal prosecutors have accused Loughlin and her husband, Mossimo Giannulli, of agreeing to pay bribes totaling $500,000 to boost their daughters’ chances of getting into USC. They’re among 50 people charged in the $25 million scandal.
