Former secretary of state Hillary Rodham Clinton was paid $300,000 to speak to students and faculty at the University of California Los Angeles in March, the university confirmed Friday.

UCLA spokesman Jean-Paul Renaud said Clinton's fee was paid through a private endowment established for a lecture series by Meyer Luskin, an investor and president of Scope Industries, a food waste recycling company.

In 2012, former president Bill Clinton was paid $250,000 to deliver the inaugural address in the Luskin lecture series, Renaud said.

In both instances, Renaud said, the Clintons' fees went to the Bill, Hillary and Chelsea Clinton Foundation.

"It came from private money," Renaud said. Although UCLA is a public university, he added, "No public funds were used for it -- no tuition dollars, no state funds."

News of Hillary Clinton's fee was first reported Friday afternoon by The Wall Street Journal. It comes amid growing scrutiny of Clinton's personal wealth and speaking fees.

Clinton is being paid $225,000 to speak at the University of Nevada at Las Vegas. Although her office said she is directing the funds to the Clinton Foundation, her pay has drawn protests from student leaders. Jon Ralston, an influential television journalist in Nevada, called Clinton's fee "grotesque" and "obscene."

A spokesman for Clinton did not immediately respond to a request for comment.

On Friday, The Washington Post published a comprehensive review of former President Bill Clinton's paid speeches. He has earned $104.9 million delivering 542 speeches around the world between leaving the White House in January 2001 and Hillary Clinton's departure as secretary of state in January 2013, the Post review found.
