Women\u0026#039;s advocacy group UltraViolet called on MSNBC to fire host Chris Matthews Wednesday after he cast doubt on accusations of harassment leveled at billionaire Michael Bloomberg\u0026nbsp;following Tuesday evening\u0026#039;s Democratic debate.The comments came as\u0026nbsp;Matthews interviewed Sen. Elizabeth Warren after the debate. Warren during the debate\u0026nbsp;launched her second attack on Bloomberg over multiple allegations of harassment and discrimination at his media company and the non-disclosure agreements employees signed as part of legal settlements.Demanding to\u0026nbsp;know how Warren\u0026nbsp;could be sure the accusations against Bloomberg are true, Matthews offered \u0022a textbook example of why people don\u0026#039;t report sexual misconduct,\u0022 tweeted\u0026nbsp;HuffPost\u0026nbsp;reporter Marina Fang.Watch:I believe the women—and I want to hear their stories. pic.twitter.com/PjDUlXXHWi— Elizabeth Warren (@ewarren) February 26, 2020Calling Bloomberg the \u0022riskiest\u0022 candidate in the Democratic field and one who won\u0026#039;t be able to earn voters\u0026#039; \u0022trust,\u0022 Warren on the debate stage had recounted her own story of facing pregnancy discrimination early in her teaching career.Although there were no federal laws to protect her, Warren said, \u0022At least I didn\u0026#039;t have a boss who said to me, \u0026#039;Kill it,\u0026#039; the way that Mayor Bloomberg is documented to have said to one of his pregnant employees.\u0022Warren later said Bloomberg\u0026#039;s former employee\u0026#039;s \u0022own words\u0022 were evidence that he had urged the woman to get an abortion. Another former employee, David Zielenziger, told the Washington Post that he had also witnessed the exchange, and said he viewed it as \u0022outrageous\u0022 at the time.Nevertheless, in her post-debate interview with MSNBC, Matthews grilled Warren about the veracity of the claim.\u0022You believe he\u0026#039;s lying?\u0022 Matthews asked. \u0022Why would he lie? Because just to protect himself? ... I just want to make sure that you\u0026#039;re clear about this.\u0022\u0022We have gone on and on and on where people say, \u0026#039;Oh, I can\u0026#039;t really believe the women.\u0026#039; Really? Why not?\u0022 Warren said. \u0022Why would she lie?\u0022Matthew\u0026#039;s \u0022refusal to believe women,\u0022 as well as his own history of sexual harassment allegations, should be considered grounds for his dismissal, UltraViolet executive director Shaunna Thomas said in a statement.\u0022MSNBC needs to fire Chris Matthews. Today,\u0022 said Thomas.\u0026nbsp;\u0022He is not fit to continue to cover this election. MSNBC can and must do better, and they can start by firing Chris Matthews.\u0022Others on social media echoed the call and condemned Matthews for his line of questioning, which, Massachusetts congressional candidate Brianna Wu tweeted, put Warren \u0022under fire, not Bloomberg.\u0022Fire Chris Matthews. pic.twitter.com/0p4wypUf5w— Zara Rahim (@ZaraRahim) February 26, 2020Last night, @HardballChris GRILLED Elizabeth Warren for bringing up Bloomberg’s “Kill it” comment to a pregnant employee. She was under fire, not Bloomberg. Matthews settled a similar lawsuit in 2017. Lack of women in media leadership REALLY MATTERS. https://t.co/oVm0oBja14— Brianna Wu (@BriannaWu) February 26, 2020The wildest thing about the Chris Matthews/Warren exchange is Matthews asking why Bloomberg would lie ... about whether he told a pregnant employee, referring to her fetus, to \u0022kill it.\u0022I kind of feel like that question answers itself. https://t.co/W5a7GqRS9r— Angus Johnston (@studentactivism) February 26, 2020This line of questions from Chris Matthews is insane. He actually cannot wrap his head around believing women. https://t.co/ZjKazAAK2l— Lauren Duca (@laurenduca) February 26, 2020Warren reiterated her own experience in her conversation with Matthews, reminding him, \u0022I\u0026#039;ve been on her end of it... It happens all across the country and men all across this country say, \u0026#039;Oh my gosh, he would never have said that.\u0026#039;\u0022\u0022We applaud Senator Warren for standing with survivors of workplace abuse and bringing up these comments at the debate—it is clear that she supports and believes women—something that every Democratic nominee for president can and must do,\u0022 Thomas said.
