In the span of a little over 15 minutes, six female Democratic senators called on their colleague Al Franken (D-MN) to step down from his position. Sens. Kirsten Gilibrand (D-NY), Mazie Hirono (D-HI), Claire McCaskill (D-MO), Maggie Hassan (D-NH), Kamala Harris (D-CA), and Patty Murray (D-WA) all issued statements saying that they believe that members of the Senate should be held to higher standards and that Franken has not met these standards.
Sen. Gilibrand's statement came first, saying that she's spent "a lot of time reflecting" about the wave of sexual assault and harassment allegations. While she thinks that Franken is entitled to the Ethics Committee hearing he requested in the wake of the initial allegation against him, she thinks he should not be in the Senate. She released a longer statement on her official Facebook page.
Shortly after, Hawaii's Sen. Hirono tweeted her own statement saying Franken should "step aside." She said that she's "struggled" with this as Franken is one of her friends, but she believes he has mistreated women in the past. She cited the TIME Magazine's selection of "The Silence Breakers" as part of her rationale for speaking out now against Franken. Hirono said it was important to "create a culture" that respects women as equals to their male counterparts.
McCaskill was blunter than her colleagues, and tweeted out that Franken should resign.
Sen. Hassan echoed her colleagues and said that it was "clear" Franken has a "pattern of egregious and unacceptable behavior towards women," and therefore should leave the Senate.
Sen. Harris said she believed it would be the "best thing" for Franken to leave the Senate.
Sen. Murray said that she was "shocked and appalled" by Franken, and said that it was time for him to "step aside." Murray said that the Senate should "lead by example."
Notably, Franken's fellow Minnesotan Sen. Amy Klobuchar (D) has not yet issued a statement. (See 12:59 p.m. update)
This post will be updated if anyone else calls for Franken's resignation.
