Criticism of Sen. Al Franken (D-Minn) is piling up after two more women accused the former comedian of inappropriate touching.
One woman said Franken groped and forcibly kissed her in 2006, and another said he grabbed her behind while posing for a photo. This week two more women said Franken did the same thing during photo ops in 2007 and 2008.
Democrats and Republicans have condemned the senator's behavior, some calling for him to resign.
Sen. Chuck Schumer (D-N.Y.) and Sen. Dick Durbin (D-Ill.) called for the Senate Ethics Committee to investigate Franken and said sexual harassment should never be tolerated.
Many female Democratic senators, including Patty Murray and Claire McCaskill weighed in, saying they are concerned and disappointed in Franken's actions.
"It's always a great disappointment when leaders you like and admire do bad stuff," said Democratic consultant Mike Lux. "If more incidents come to light, he's got a real problem."
"I think the apology tour that he's going on just isn't working," Boyd Matheson, former chief of staff to Sen. Mike Lee (R-Utah), said on "The Daily Briefing" Friday.
"I've met tens of thousands of people and taken thousands of photographs, often in crowded and chaotic situations," Franken's apology statement read. "I'm a warm person; I hug people. I've learned from recent stories that in some of those encounters, I crossed a line for some women -- and I know that any number is too many."
"I've thought a lot in recent days about how that could happen, and recognize that I need to be much more careful and sensitive in these situations," the statement said, adding that he hopes to regain Minnesotans' trust.
The Senate Ethics Committee is considering an investigation into the allegations.
