Some progressive groups are demanding his resignation after a second woman accuses the Democratic senator of sexual misconduct.

The left is starting to turn against Sen. Al Franken after a second woman accused him of sexual misconduct, with some liberal groups calling on the Democrat to resign.

Franken was already facing calls from both parties for a Senate ethics investigation after he was accused of forcibly kissing radio anchor Leeann Tweeden in 2006. But a fresh accusation Monday that Franken groped a woman named Lindsay Manz while they posed for a picture at the Minnesota State Fair in 2010 — the first involving his alleged conduct as a senator — triggered demands from some liberals for the second-term senator to step down.

“We believe Lindsay Menz. We believe Leeann Tweeden,” tweeted Indivisible, the progressive advocacy group that’s gained prominence challenging President Donald Trump this year. “Senator @alfranken should be held accountable and he should resign.”
