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.
Democratic National Committee Chairman Tom Perez also tweeted that Franken should step down.
In addition, Senate Majority Leader Mitch McConnell said he does not believe Franken "can effectively serve the people of Minnesota in the U.S. Senate any longer." Sen. Susan Collins, R-Maine, also said Franken should resign.
In the statements, the senators used words like "egregious" and "unacceptable" to describe Franken's behavior.
The unidentified former aide who spoke to Politico said the incident took place after a taping of Franken's radio show, before he was a senator.
"'It's my right as an entertainer,'" the woman says Franken told her after she avoided his kiss.
In response to the claim, Franken said: "This allegation is categorically not true and the idea that I would claim this as my right as an entertainer is preposterous. I look forward to fully cooperating with the ongoing ethics committee investigation."
Franken is among multiple members of Congress who have faced harassment accusations recently. Rep. John Conyers, D-Mich., stepped down Tuesday after more than 50 years in Congress following former staffers' allegations of misconduct.
The push for Franken's resignation also comes as ex-Judge Roy Moore runs for Senate in Alabama amid allegations of sexual misconduct with teenagers when he was in his 30s decades ago.
Time magazine on Wednesday named "The Silence Breakers" — those who have come forward with their stories about being victims of pervasive sexual harassment — as 2017 Person of the Year.
