The Full House star's Instagram also went abruptly silent, with all of her posts first disappearing before the entire profile evaporated.
Lelling said the scam has cost less privileged students an education of their dreams.
Singer ran a steady business getting students into Yale, Stanford, Georgetown and the University of Southern California.
College coaches, including one longtime Yale coach, and others have been charged in a sweeping admissions bribery case unsealed in federal court.
The affidavit alleges two days after their oldest daughter was accepted to USC as a crew recruit a payment was sent to the Senior Women's Associate Director of USC in the amount of $500,000. According to Bloomberg, he earned an estimated $8.2 million in 2017. "In many instances, the students taking the exams were unaware that their parents had arranged for this cheating".
Those charged included several athletic coaches.More news: Paul Manafort Receives His First Sentence
The FBI's Boston office said on Twitter that dozens of people have been charged in the nationwide college admissions cheating and recruitment scandal. No students were charged. "There can be no separate college admission system for the wealthy, and I'll add that there will not be a separate criminal justice system either".
Prosecutors say the consultant represented to parents that the scheme had worked successfully more than 800 times. "This was shopping for name-brand product and being willing to spend whatever it took". Singer, 58, also served as the CEO of Key Worldwide Foundation, a nonprofit he established as a purported charity, prosecutors said. He was expected to plead guilty Tuesday afternoon, according to prosecutors at a press conference.
Singer also paid coaches to designate unqualified applicants as athletes and would sometimes help families fabricate a profile for their children, including using Photoshop to digitally alter stock photos with an applicant's face, the US attorney said.
Officials say parents spent anywhere from $200,000 to $6.5 million to guarantee their children's admission.
The parents were among 50 people arrested in the alleged scheme, which also involved bribes paid to coaches. The colleges themselves are not targets, Lelling said.
"Stanford has been cooperating with the Department of Justice in its investigation and is deeply concerned by the allegations in this case", school officials stated. He did not elaborate. "Once the companies that administered those exams had agreed to the extra time, Singer arranged for the child to take the exam individually with one of the proctors he had bribed either at a location in Houston or at a location in California", said Andrew Lelling, U.S. attorney in MA.
