The attorney leading Republican presidential candidate Donald Trump's defense in a civil fraud suit related to Trump University donated to Hillary Clinton's presidential campaign earlier this year.

According to the Center for Responsive Politcs, Daniel Petrocelli gave $2,700 to the Clinton campaign this past January, two months after he was brought onto the case. Yahoo News, which first reported the donation, also reported that Petrocelli has been a financial backer of Clinton's campaigns dating back to her first run for the Senate in 2000.

Trump has been on the defensive for most of this week over comments he made about U.S. District Court Judge Gonzalo Curiel, who is presiding over the case. He said that Curiel cannot be impartial in the case, considering Trump has vowed to build a wall along the southern U.S. border to keep out Mexican “rapists” and “drug dealers.”

On Tuesday, Trump claimed his earlier remarks had been "misconstrued."

In an interview with Fox News' Sean Hannity Tuesday, Trump turned his ire to the law firm that filed the class-action suit, Robbins Geller Rudman & Dowd.

"The law firm gave hundreds of thousands — I think it was $900,000 or $700,000 — in speaking fees to the Clintons," Trump said. "Plus, they contributed tremendous amounts of money to the campaign ... The whole thing is disgusting."

In fact, the website LawNewz reported that California-based Robbins Geller Rudman & Dowd paid the Clintons a total of $675,000 for speeches dating back to 2009.

Petrocelli is best known for successfully arguing that ex-NFL star O.J. Simpson should be held criminally liable for the 1994 stabbing deaths of his ex-wife and her friend, despite Simpson being acquitted of murder in a criminal trial.
