'Completely unacceptable': Senators react to allegations that Al Franken kissed and and groped a TV host without consent

Franken in a fuller statement apologized again and asked that an ethics investigation be launched. He said he will "gladly cooperate." Below is the full statement:

"The first thing I want to do is apologize: to Leeann, to everyone else who was part of that tour, to everyone who has worked for me, to everyone I represent, and to everyone who counts on me to be an ally and supporter and champion of women. There's more I want to say, but the first and most important thing—and if it's the only thing you care to hear, that's fine—is: I'm sorry.

"I respect women. I don't respect men who don't. And the fact that my own actions have given people a good reason to doubt that makes me feel ashamed.

"But I want to say something else, too. Over the last few months, all of us—including and especially men who respect women—have been forced to take a good, hard look at our own actions and think (perhaps, shamefully, for the first time) about how those actions have affected women.

"For instance, that picture. I don't know what was in my head when I took that picture, and it doesn't matter. There's no excuse. I look at it now and I feel disgusted with myself. It isn't funny. It's completely inappropriate. It's obvious how Leeann would feel violated by that picture. And, what's more, I can see how millions of other women would feel violated by it—women who have had similar experiences in their own lives, women who fear having those experiences, women who look up to me, women who have counted on me.

"Coming from the world of comedy, I've told and written a lot of jokes that I once thought were funny but later came to realize were just plain offensive. But the intentions behind my actions aren't the point at all. It's the impact these jokes had on others that matters. And I'm sorry it's taken me so long to come to terms with that.

"While I don't remember the rehearsal for the skit as Leeann does, I understand why we need to listen to and believe women’s experiences.

"I am asking that an ethics investigation be undertaken, and I will gladly cooperate.

"And the truth is, what people think of me in light of this is far less important than what people think of women who continue to come forward to tell their stories. They deserve to be heard, and believed. And they deserve to know that I am their ally and supporter. I have let them down and am committed to making it up to them."

Shaheen told reporters she couldn't comment because she is a member of the Ethics Committee.

Kaine told reporters that the idea of an ethics investigation "has merit."

When asked whether Franken had done enough to apologize, Kaine said, "That's a hard question. The sufficiency of an apology is measured by what the person thinks of it. I'm not going to judge the sufficiency of the apology, but the behavior is unacceptable."

Murray also said she backed an ethics investigation and noted that Franken's apology was appreciated but insufficient.

"This is unacceptable behavior and extremely disappointing. I am glad Al came out and apologized, but that doesn't reverse what he's done or end the matter," she said in a statement.

"I support an ethics committee investigation into these accusations and I hope this latest example of the deep problems on this front spurs continued action to address it."

"I just heard about it. I had no idea at all. I just heard. They just told me about it. I'm sure we're going to hear a lot more about it," Manchin told reporters.

Gillibrand told reporters the allegations are "deeply concerning" and that she believes Tweeden. She said Franken's apology was not sufficient, and called for an investigation.

Not all senators appeared critical of Franken. Whitehouse told reporters, "You guys need to find something more interesting.

McCaskill tweeted that she was "shocked and concerned" by the allegations.

"The behavior described is completely unacceptable," she said. "Comedy is no excuse for inappropriate conduct, and I believe there should be an ethics investigation."

Schumer backed McConnell's call for an investigation. "Sexual harassment is never acceptable and must not be tolerated," he said in a statement.

"I hope and expect that the Ethics Committee will fully investigate this troubling incident, as they should with any credible allegation of sexual harassment."

McConnell led the way on Thursday with a call for an ethics committee to convene.

"As with all credible allegations of sexual harassment or assault, I believe the Ethics Committee should review the matter. I hope the Democratic Leader will join me on this," McConnell said in a statement. Regardless of party, harassment and assault are completely unacceptable — in the workplace or anywhere else."
