Democratic Senator and ex-comedian Al Franken has said he plans to quit “in the coming weeks” after string of sexual harassment allegations.
“I am proud that during my time in the Senate that I have used my power to be a champion of women,” the Minnesota senator said from the US Senate floor.
The announcement came after dozens of Democrats called on him to resign.
He is the most prominent political figure to resign amid a wave of sexual misconduct allegations.
“Today I am announcing that in the coming weeks I will be resigning as a member of the United States senate,” he told his colleagues on Thursday.
“I may be resigning my seat but I am not giving up my voice.”
The former Saturday Night Live comedian and two-term senator has apologised to several women who have accused him of groping and sexual harassment, but he faced mounting pressure to resign after a new allegation emerged on Wednesday.
“Some allegations against me simply are not true,” he said adding “there has been a very different picture of me painted over the last couple of weeks”.
“But I know who I really am,” he said.
“I’m going to be just fine.”
Mr Franken is not the only US politician to have found himself accused of sexual harassment in recent weeks.
On Tuesday, Michigan Democrat John Conyers, announced that he would resign amid claims of sexual harassment made by his congressional aides.
Republican Alabama Senate candidate Roy Moore has also been accused of sexual impropriety.
Seven women have come forward to accuse the former Alabama Supreme Court judge of sexual misconduct decades ago, including one woman who claims he molested her when she was 14 years old while he was in his 30’s and working as an Alabama prosecutor.
Another woman alleges the judge had tried to rape her after he offered her a ride home from her job as a waitress.
