Minnesota Sen. Al Franken will resign from the United States Senate "in the coming weeks" he announced Thursday, a day after a number of his Democratic colleagues called for him to step down amid mounting allegations of sexual misconduct against women.

"Today I am announcing that in the coming weeks, I will be resigning as a member of the United States Senate," Franken said on the Senate floor. "It's become clear that I can't both pursue the Ethics Committee process and at the same time remain an effective senator for [the people of Minnesota]."

The allegations against Franken began less than three weeks ago, with the account of a Los Angeles radio host who described his actions while the two were on a USO trip together in 2006. Though he apologized, acknowledged some wrongdoing and called for an ethics investigation to be initiated, he resisted early calls for his resignation, even after additional accusations of misconduct surfaced.
