Three more Senate Democrats have vowed to donate to charity campaign contributions they received from Hollywood film producer Harvey Weinstein after it was revealed Thursday there have been three decades of previously undisclosed sexual allegations made against him.

Sens. Richard Blumenthal of Connecticut, Martin Heinrich of New Mexico and Elizabeth Warren of Massachusetts said they would donate the same amount Weinstein contributed to their campaigns to charity, the New York Times reported. Their decisions follow that of Democratic Sen. Patrick Leahy of Vermont, whose office said Thursday he would donate $5,600 in campaign contributions from Weinstein to charity.

Blumenthal and Heinrich are planning to donate $5,400 to charity, and Warren is going to give $5,000 to charity.

Some of the Democratic lawmakers will make contributions to organizations that work domestic violence victims, according to the New York Times.

More Democrats are expected to get rid of Weinstein's campaign contributions.

The Hollywood producer is a major Democratic donor who contributed to both to candidates and party committees over the years. According to campaign finance records compiled by the Center for Responsive Politics, Weinstein has given the Democratic National Committee more than $245,000 in donations since 1994. He's also donated $103,900 to the Democratic Senatorial Campaign Committee since 2002.

Former President Barack Obama, and Bill and Hillary Clinton all received campaign contributions from Weinstein, and the Hollywood producer hosted a fundraiser for Hillary Clinton during the 2016 presidential campaign at his home in Manhattan.

Other notable Democrats who have received campaign contributions from Weinstein include Sens. Chuck Schumer and Kirsten Gillibrand of New York, Al Franken of Minnesota, and Dianne Feinstein of California.
