The Republican National Committee announced Saturday that casino mogul Steve Wynn is resigning from his post as the party’s finance chairman amid allegations of sexual harassment.

The Wall Street Journal reported Friday that numerous women have accused Wynn of harassment or assault, including one manicurist who received a $7.5 million settlement. Wynn has denied the allegations, suggesting they are part of a smear campaign by his ex-wife, Elaine Wynn.

“The conduct of Elaine during the course of the pending lawsuits has been shocking and deeply disturbing to me personally and as the CEO of Wynn Resorts,” Wynn said in a statement to the Associated Press.

Wynn has long been a prolific donor to Republican candidates and a supporter of President Donald Trump. According to the AP, Wynn has contributed nearly $2.4 million to GOP candidates and party organizations around the country since 2013, including more than $600,000 last year.

“Today I accepted Steve Wynn’s resignation as Republican National Committee finance chair,” RNC chair Ronna Romney McDaniel said in a brief statement Saturday.

While McDaniel and other Republican officials pressured the Democratic Party to return donations from film producer Harvey Weinstein after allegations of sexual misconduct by him were reported last fall, the RNC did not immediately say what it will do with Wynn’s donations.
