Sen. Al Franken (D-Minn.) held a press conference on Monday to address sexual misconduct allegations that have been brought against him by several women.
Franken said he's let a lot of people down, including the people of Minnesota, his colleagues, his staff and his supporters.
"To all of you, I just want to again say I am sorry," Franken said.
He said it will take a long time to regain the trust he had built up, and he's ready to start that process by returning to work on Capitol Hill.
He said he's "tremendously sorry" that some women feel that he has done something disrespectful that has hurt them.
"I am embarrassed. I feel ashamed," Franken said. "What I'm going to do is I'm going to start my job, I'm going to go back to work, I'm going to work as hard as I can for the people of Minnesota, and I'm going to start that right now."
At least three women have accused Franken of grabbing their buttocks while they posed for photos between 2007 and 2010.
In addition, radio broadcaster Leeann Tweeden publicly accused Franken of groping her breasts and forcibly kissing her while the two were on a USO Tour in 2006.
