WASHINGTON - Yet another woman has come forward accusing Minnesota Senator Al Franken of sexual misconduct.

Tina Dupuy, a journalist, wrote in The Atlantic on Wednesday the incident happened at a Media Matters party during the first Obama inauguration.

"Tweeden’s story rang true to me. I’d told myself I was the only one. I’d been groped by Franken in 2009," she wrote.

"I only bug celebrities for pictures when it’ll make my foster mom happy. She loves Franken, so I asked to get a picture with him. We posed for the shot. He immediately put his hand on my waist, grabbing a handful of flesh. I froze. Then he squeezed. At least twice," Dupuy recalled.

"Al Franken’s familiarity was inappropriate and unwanted. It was also quick; he knew exactly what he was doing," she added.

Earlier Wednesday, Politico reported an allegation by an unnamed woman stating Franken tried to forcibly kiss her after a taping of his radio show in 2006.

The woman says Franken pursued her after her boss had left and she was collecting her belongings. She says she ducked to avoid his lips. And she says Franken told her: "It's my right as an entertainer."

The Minnesota Democrat released a statement Wednesday morning stating it was "categorically not true."

But by early Wednesday afternoon, nearly all Senate Democrats, as well as the Democratic National Committee Chair, called for Franken to resign. His office said he'll be "making an announcement" on Thursday.
