Washington Senator Patty Murray called for Senator Al Franken to step down Wednesday.

Murray said she was “shocked and appalled by Senator Franken’s behavior” in a tweet.

“It’s clear to me that this has been a deeply harmful, persistent problem and a clear pattern over a long period of time. It’s time for him to step aside,” she went on to say.

The Minnesota Demcrat was the first senator to be publicly accused of sexual assault or harassment in the wake of the aftermath of the Harvey Weinstein harassment scandal that has rocked the country.

Lindsay Menz, a 33-year-old from Texas, told CNN that the senator pulled her in close and grabbed her buttocks while the two were posing for a picture at the Minnesota State Fair in 2010. Leeann Tweeden said Franken, while they were on a USO tour in the Middle East to entertain U.S. troops, stuck his tongue down her throat and pretended to grope her while she was sleeping in a later picture.

Last month Franken dismissed a question about what type of behavior should merit resignation for any lawmaker. He pledged to cooperate with a Senate Ethics Committee investigation and said he “is open” to making the results public.
