The senator added that although he has a different recollection of rehearsals for the skit, "I understand why we need to listen to and believe women's experiences".
She states both incidents occurred while they were on tour entertaining USA troops in Iraq, when Franken was still a well-known professional comedian.
Tweeden is now a broadcaster for KABC radio in Los Angeles and anchors the McIntyre in the Morning show. Tweeden also posted a picture in which Franken is shown grinning into a camera with his hands on a sleeping Tweeden's breasts. "As to the photo, it was clearly meant to be amusing but wasn't", he says.
The incidents described by Tweeden took place before Franken took public office, though the allegations have prompted several senators to call for the Senate Ethics Committee to investigate the matter.
"I certainly don't remember the rehearsal for the skit in the same way, but I send my sincerest apologies to Leeann", Franken says.
Tweeden is the daughter of a service member, and she says that she's passionate about the troops and their mission overseas. It isn't amusing. It's completely inappropriate.
Franken is a longtime comedian and "Saturday Night Live" writer who won a Minnesota seat in the U.S. Senate after a lengthy recount in 2009.
"I am asking that an ethics investigation be undertaken, and I will gladly cooperate".
She added that she saw Franken a couple of years after the incident occurred, at a USO gala. "I said something like, 'Relax Al, this isn't SNL ... we don't need to rehearse the kiss'". "I shouldn't have done it", he said.
Democrats throughout the morning weighed in with disappointment toward Franken and calls for an Ethics Committee investigation. "I hope the Democratic leader will join me on this".
Tweeden credited Congresswoman Jackie Speier's (D-California) account of being assaulted when she was a young Congressional aide as inspiration to come forward.
For Democrats, the swift requests for an investigation into Franken were necessary to avoid the suggestion of hypocrisy, since majority have condemned Republican Senate candidate Roy Moore, who has been accused of making advances to teenagers when he was a local prosecutor in his 30s.
