The Huffington Post website on Wednesday cited two unnamed women who said that U.S. Sen Al Franken grabbed their buttocks in separate incidents.

Each woman spoke on condition of anonymity about events they said occurred during Franken's first Senate campaign.

One woman said Franken groped her when he posed for a photo with her after a June 2007 event hosted by the Minnesota Women's Political Caucus in Minneapolis.

A second woman told HuffPost that Franken cupped her butt with his hand at a 2008 Democratic fundraiser in Minneapolis, then suggested the two visit the bathroom together.

Franken issued a statement Wednesday saying, "It's difficult to respond to anonymous accusers, and I don't remember those campaign events." He added, "I can categorically say that I did not proposition anyone to join me in any bathroom."

On Monday, Lindsay Menz accused Franken of groping her at the Minnesota State Fair in 2010.

"My story is eerily similar to Lindsay Menz's story," one accuser said. "He grabbed my buttocks during a photo op."

The two most recent accusers, who said they were not familiar with each other's stories, both spoke on condition of anonymity. Their stories are remarkably similar — and both women have been telling them privately for years, they said.
