TV host and sports broadcaster Leeann Tweeden accused Franken of groping her while she slept during a December 2006 USO tour to entertain the U.S. military, and provided photo evidence to prove it.
"I felt violated all over again. Embarrassed. Belittled. Humiliated," wrote Tweeden. "How dare anyone grab my breasts like this and think it's funny?"
During a separate incident, Tweeden said Franken tried to kiss her as part of a rehearsal for a skit and "aggressively stuck his tongue" in her mouth.
Years after the abuse, Franken was busy on Twitter lecturing Republicans about how they needed to "respect women".
"The GOP is showing that they don't respect women's freedom," he tweeted back in January.
In another tweet, Franken decried the "sexual harassment" of women.
In another tweet endorsing Hillary Clinton's presidential campaign, Franken labeled Hillary "a progressive voice that will fight back against attacks on women's rights."
A search of Franken's Twitter history shows he has repeatedly invoked his advocacy for women as a political tool.
