More than 25 Democratic senators and the party's chief urged Sen. Al Franken to resign Wednesday following the latest sexual misconduct allegation against him.
After the resignation calls, Franken's office said the senator would make an "announcement" on Thursday. It didn't elaborate.
Earlier Wednesday, Politico reported that a former Democratic congressional aide is accusing the Minnesota Democrat of forcibly trying to kiss her 11 years ago, adding to a string of allegations against him.
In a statement before Democratic women started the calls for his resignation, Franken denied the latest accusation against him.
In a succession of statements Wednesday, more than 25 of Franken's Senate Democratic colleagues — about half of the party's caucus — pushed for him to step down. Among them were Minority Leader Chuck Schumer of New York, Dick Durbin of Illinois and Patty Murray of Washington, the top ranking Senate Democrats.
"I consider Senator Franken a dear friend and greatly respect his accomplishments, but he has a higher obligation to his constituents and the Senate, and he should step down immediately," Schumer said in a statement.
