New Groping Allegation against U.S. Senator Al Franken

A second woman has said she was groped by U.S. Senator Al Franken, who is already facing a potential ethics investigation over an earlier allegation, CNN reported on Monday.

Lindsay Menz said she took a photograph with the senator a fair in Minnesota in 2010, and that Franken "pulled me in really close, like awkward close, and as my husband took the picture, he put his hand full-fledged on my rear."

Franken told the channel that he did not remember taking the photo with Menz, and that he felt "badly that Ms Menz came away from our interaction feeling disrespected."

Sports broadcaster and former model Leeann Tweeden had previously accused the former comedian of touching her while she slept and kissing her without her consent in 2006 -- the latest in a string of sexual assault allegations against prominent American men.

Franken's rise from funnyman to darling of the political left has been thrown into doubt by the allegations and the likely opening of a Senate ethics investigation that could see him fined, stripped of committee posts or even expelled.
