Phil Mickelson says he worked with the company at the center of a college bribery scandal but denounced founder Rick Singer and says he was not part of any fraudulent activity, just two days after the Department of Justice handed down an indictment of 33 affluent parents.

In a statement on Twitter on Thursday, Mickelson expressed his disappointment in Singer and his company, which guided the PGA Tour star’s family through the college admission process.

“Our family, along with thousands of others, used Rick Singer’s company to guide us through the college admission process,” Mickelson’s statement said. “We are shocked by the revelations of these events. Obviously, we were not part of this fraud, our kids would disown us if we ever tried to interfere.”

Mickelson and wife Amy have three children. The couple’s oldest daughter Amanda attends Brown University.

In 2017, Mickelson famously skipped the U.S. Open to attend Amanda’s high school graduation.

He posted the statement Thursday afternoon after he recorded an opening-round 74 at The Players Championship in Ponte Vedra, Fla.

Singer, a California businessman who ran a college prep center and nonprofit foundation —  the Key Worldwide Foundation — was at the center of the hundreds of pages of court documents released Tuesday when federal prosecutors announced details of the bribery scheme.

The documents allege Singer received payments from various wealthy and famous clients in exchange for finding spots for their children in prestigious universities. Actresses Lori Loughlin and Felicity Huffman are two of the high-profile names indicted alongside CEOs, lawyers and Division I college coaches and administrators.

Singer, 56, pleaded guilty in Boston federal court Tuesday to charges of money laundering, obstruction of justice, racketeering and conspiracy to defraud the United States, according to U.S. attorney for the district of Massachusetts Andrew Lelling.
