"He came at me, put his hand on the back of my head, mashed his lips against mine and aggressively stuck his tongue in my mouth", Tweeden wrote.
Tweeden wrote in a column on Tuesday that Franken forcefully kissed her and groped her without permission in 2006. "But there's nothing amusing about sexual assault".
She posted a photo taken at the time of Franken mugging for the camera with his hands above her breasts as she sat in the military aircraft wearing a flak jacket with eyes closed.
"I couldn't believe it. I'm not demanding any of that", Tweeden said.
She said she pushed Franken away but felt disgusted and violated.

Tweeden said Franken wrote a skit that included a kiss between the two and said he insisted upon rehearsing it, which she at first resisted.
"While debating whether or not to go public, I even thought to myself, so much worse has happened to so many others, maybe my story isn't worth telling?"
After Senate Majority leader Mitch McConnell (R-Ky.) said the Ethics Committee should review the matter, and several prominent Democratic senators joined that call, Franken issued a second statement in which he agreed.
"Sexual harassment is never acceptable and must not be tolerated", Schumer said.
Franken has apologized and says he'll cooperate with an ethics investigation.

"The behavior reported today is unacceptable and deeply disappointing".
"He had a chance to apologize to me then. I'm not asking for him to step down for senator. if someone else calls for that, but that's not what I'm asking". He said to me, 'We need to rehearse the kiss.' I laughed and ignored him.
