A radio broadcaster accused U.S. Sen. Al Franken on Thursday of touching her breasts while she slept and forcing a kiss on her in 2006 when he was still a comedian and the two were preparing to perform before U.S. troops in the Middle East.

Anchor Leeann Tweeden related her experience in a first-person account on the website of Los Angeles station KABC amid outrage over numerous reports of sexual misconduct by powerful men from Hollywood to Capitol Hill.

Franken, a Democrat, issued an apology. The Senate's Democratic and Republican leaders called on the Ethics Committee to review the allegations and Franken said he would cooperate.
