ST. PAUL, Minn. (AP) — Two Democratic gubernatorial candidates in Minnesota are calling on U.S. Sen. Al Franken to resign amid allegations of sexual harassment.

State Auditor Rebecca Otto and state Rep. Erin Murphy issued statements saying their fellow Democrat should lead by example and step down. Otto calls Franken a friend, but says “we can’t have a double standard.”

Los Angeles radio news anchor Leeann Tweeden alleged Thursday that Franken forcibly kissed her during a skit rehearsal when they were on a 2006 USO tour. Tweeden also posted a picture online showing Franken grinning into the camera with his hands on her chest as she slept wearing a flak vest.

Franken quickly apologized to Tweeden and his constituents while maintaining that he remembered the rehearsal differently.
