Menz's allegation comes days after a Los Angeles broadcaster, Leeann Tweeden, accused Franken of forcibly kissing her during a 2006 USO tour.
Menz was emphatic that she "absolutely" would not have chose to share her story had Tweeden not done the same.
MINNEAPOLIS (AP) - A group of women who worked alongside Al Franken on NBC's "Saturday Night Live" have signed a statement of support for the Minnesota senator.
"It wasn't around my waist". It wasn't around my hip or side. "It was definitely on my butt", she said, recalling that the brazen act lasted three or four seconds.
"I was like, oh my God, what's happening".
In the photo of Menz and Franken, the lower halves of their bodies are not shown. Franken said he was sorry if Menz felt disrespected.
The 66-year-old former comic apologized to Menz if he made her feel "disrespected". Tweeden also released a photo showing Franken grabbing her chest through her protective vest while she was sleeping. When her sister observed how close together she and Franken were posing, Menz responded: "Dude - Al Franken TOTALLY molested me!"
"I was upset", said husband Jeremy Menz after the incident. Franken already faced a Senate ethics investigation over Tweeden's allegation, but the Menz allegation is potentially more damaging for Franken because it would be behavior that occurred while he was in office. Congressional leaders from both parties called for a formal inquiry but stopped short of calling on Franken to resign. "There's no excuse", he said. "Now, I know this photo looks bad, but remember, it also is bad". But she said the recent spate of women who have come forward in recent weeks about their own experiences of sexual harassment by powerful men had encouraged her to reveal her own story. The couple voted past year for Donald Trump, and Menz said she has voted for Minnesota Sen.
