(NBC News) A U.S. Senator is asking his colleagues to investigate his own behavior after new allegations of sexual misconduct.
Senator Al Franken apologizing in a statement after being accused of groping Los Angeles radio personality Leann Tweeden during a 2006 USO tour
"I'm sorry," he writes. "I respect women. I don't respect men who don't."
Franken's calling for his own ethics investigation.
"That's what you have an ethics committee for, and I'm happy that he's said, 'Yeah I'll cooperate,'" said Senator Tim Kaine, (D) Virginia.
"They're serious allegations, they need to be investigated," said Senator Deb Fischer, (R) Nebraska.
"This kind of conduct should not be tolerated by anyone or any public official," said Senator Catherine Cortez Masto, (D) Nevada.
His accuser accepted the apology after detailing what she says happened.
"He mashed his lips against my face and he stuck his tongue in my mouth so fast," said Leann Tweeden, Franken accuser.
President Donald Trump tweeted overnight, "the Al Franken-Stien picture is really bad, speaks a thousand words. Where do his hands go in pictures ... while she sleeps?"
Trump added that last week Franken was "lecturing anyone who would listen about sexual harassment."
Some wonder if a wave of public accusations could lead to more victims.
"The floodgates are really open right now it could lead to a lot of false accusations that really harm an innocent person," said Former GOP Vice Presidential Candidate Sarah Palin.
Franken, not innocent by his own admission, called his own behavior disgusting.
Despite White House statements, President Trump still hasn't commented personally or answered questions about the sexual misconduct allegations against Alabama senate candidate Roy Moore.
