A former Georgetown tennis coach is accused of accepting bribes in exchange for recruiting students seeking admission to the university, some of whom did not even play competitive tennis. Gordon Ernst reportedly received a total of $2.7 million between 2012 and 2018 from William Singer, the man at the center of a nationwide college acceptance scheme involving dozens of parents (including celebrities), two standardized test administrators, one college administrator, and several college sports coaches.

In exchange for nearly $3 million, Ernst allegedly accepted 12 of Singer’s clients as competitive tennis players at Georgetown (despite the fact that some of them were not tennis players to begin with), according to the indictment.

Singer, a man from Sacramento, allegedly masterminded this college acceptance scam. Here’s how prosecutors say it worked: Singer would accept payments from parents for a sham charitable organization, and then use the money to bribe college sports coaches, college administrators, and standardized test proctors and administrators. His clientele is a cadre of wealthy people seemingly determined to buy their children into elite colleges like Yale, Stanford, University of California Los Angeles, Georgetown, and University of Southern California. They allegedly paid Singer hundreds of thousands of dollars each, sometimes much more than that. Among the accused parents are actresses Lori Loughlin and Felicity Huffman.

Singer allegedly sent bribes to Ernst via U.S. mail, at least once to his home address in Falmouth, Massachusetts, falsely labeling them as consulting fees. Here’s an example, from the indictment: In August 2015, an applicant to Georgetown sent Ernst an email that had been drafted by Singer. That email falsely touted the applicant’s tennis abilities, when in fact the applicant did not play competitive tennis. Ernst forwarded that email to an admissions officer at Georgetown, and a few days later, wrote the same admissions officer to “confirm my usage of three spots” for admission for tennis players. All three went to Singer’s clients that year, including the applicant mentioned above (who, again, did not play competitive tennis). WTOP was the first to note Ernst’s alleged role in the scheme.

The parents of that applicant eventually paid $400,000 to the accounts of a charitable foundation Singer had set up called the Key Worldwide Foundation, which prosecutors allege was basically a shell for these college admissions schemes. The payments were labeled as “private contributions” to the charitable organization (and therefore were also a tax write off for the parents), per prosecutors. Then, between September 2015 and August 2016, KWF paid a total $700,000 in checks to Ernst, according to court documents.

Georgetown released a statement on the matter Tuesday afternoon. “Georgetown University is deeply disappointed to learn that former Tennis Coach Gordon Ernst is alleged to have committed criminal acts against the University that constitute an unprecedented breach of trust,” the statement reads. Ernst hasn’t been a coach at Georgetown since December 2017, the university says, when Georgetown conducted an internal investigation and found that he had “violated University rules concerning admissions.”

Prosecutors are billing it as “the largest college admissions scam ever prosecuted by the Department of Justice.”
