Washington (CNN) When Harvey Weinstein was accused of sexually assaulting women nearly four months ago, Republicans called on Democratic lawmakers and committees to return contributions from the Hollywood mogul and major donor.

Now the GOP is being forced to answer for its own scandal-engulfed donor and fundraiser: Steve Wynn, the Las Vegas casino giant.

Immediately after The Wall Street Journal detailed decades' worth of sexual misconduct allegations from women who worked at Wynn's casinos, Democrats began insisting that Republicans -- and the Republican National Committee, where Wynn is finance chairman -- return Wynn's cash. Wynn has denied the allegations.

The Wynn Resorts board of directors said Friday it has formed a special committee made up of independent directors to investigate the allegations.

"Since he is finance chairman, shouldn't they have to give *all* the money back they've raised since he has been there?" Alixandra Lapp, the president of a super PAC that backs House Democrats, tweeted.
