Sen. Al Franken (D-MN) on Monday refused to speculate on whether more women would accuse him of sexual misconduct in the future.
"If you had asked me two weeks ago if any woman would come forward with allegations like this, I would have said no," he said during a press conference in Washington, D.C.
"I cannot speculate," he added of future allegations. "This has been a shock. It has been extremely humbling. I am embarrassed. I feel ashamed."
Franken also admitted he is "tremendously sorry" to multiple women who have recently accused him of groping them without their consent in the past.
"I know that I am going to have to be much more conscious in these circumstances," he said outside his Capitol Hill office. "Much more careful. Much more sensitive."
"Again, I know it's going to take a long time to regain people's trust," Franken continued. "I hope that I can start to do that today."
Franken additionally refused to speculate on what level of misconduct should prompt a senator to resign, adding that he would be "accountable" for his own actions regardless of the ultimate outcome.
"We are going to cooperate completely with the ethics investigation," he said of the probe by the Senate Ethics Committee. "I am going to try to learn from my mistakes."
"I want to be someone who adds something to this conversation," Franken added of the national debate over sexual misconduct. "I hope I can do that."
Broadcaster Leeann Tweeden earlier this month accused Franken of groping and kissing her without consent during a United Services Organization (USO) event in 2006 before he entered office.
Several other women have since alleged that Franken groped them during photo opportunities they had with the former comedian during his election campaigns or after he entered office.
Sen. Al Franken (D-MN) on Monday held a press conference in Washington, D.C., after several women have accused him of sexual misconduct this month.
The senator returned to Capitol Hill that morning, noting during an interview with Minnesota Public Radio the day before that his past behavior had "crossed a line" with some women.
