President Donald Trump’s Twitter Tuesday to Sen. Kirsten Gillibrand on Tuesday is sending his haters in the mainstream media into a tizzy, including one MSNBC host who alleges Trump “literally sexually harassed” the junior senator from his home state.

At 5:03 a.m. Tuesday, Trump wrote:

“Lightweight Senator Kirsten Gillibrand, a total flunky for Chuck Schumer and someone who would come to my office ‘begging’ for campaign contributions not so long ago (and would do anything for them), is now in the ring fighting against Trump. Very disloyal to Bill & Crooked-USED!”

The message was apparently too much for MSNBC host Mika Brzezinski, who took aim at Ivanka Trump’s focus on women in light of her father’s Twitter post.

“Who is the first woman that says I just can’t continue working here?” co-host Joe Scarborough questioned.

“Maybe it’s the force for women, maybe it’s Ivanka Trump. Maybe she will finally stand up for what is right since her father just literally sexually harassed in a cruel way a woman on Twitter,” Brezezinski cut in. “Ivanka, you stepped in there to talk for women, to speak for women, to have a platform for women.

“Where are you today?”

The blowup comes a day after Gillibrand called on the president to resign amid accusations he sexually assaulted several women before he was president. Several women held a press conference on Monday to revisit the accusations, which Trump addressed during his 2016 campaign.

“President Trump has committed assault, according to these women, and those are very credible allegations of misconduct and criminal activity, and he should be fully investigated and he should resign,” the senator told CNN.

Like Brzezinski, Gillibrand alleged Trump’s Twitter post on Tuesday constituted a sexist attack, and said it only strengthens her resolve to remove him from office.

“It was a sexist smear attempting to silence my voice, and I will not be silenced on this issue. Neither will the women who stood up to the president yesterday,” she said, according to NBC News. “Their voices also will not be silenced, and neither will the millions of women and men who have marched against the president and his policies.”

Other Democratic lawmakers, including Massachusetts Sen. Elizabeth Warren, also came to Gillibrand’s rescue, including Massachusetts Sen. Elizabeth Warren, who insinuated the president’s comments were designed to “slut shame” her colleague.

“Are you really trying to bully, intimidate and slut-shame @SenGillibrand? Do you know who you are picking a fight with? Good luck with that, @realDonaldTrump. Nevertheless, #shepersisted,” Warren posted to Twitter.

“The Me Too movement has arrived,” Florida Democrat Lois Frankel said during a press conference by the House’s Democratic Women’s Working Group to fire back at the president about the Gillibrand tweet.

“Sexual abuse will not be tolerated whether it’s by a Hollywood producer, the chef of a restaurant, a member of Congress or the President of the United States. No man or woman is above the law.”

Trump press secretary Sarah Sanders told reporters Tuesday that the situation is basically liberals twisting president’s tweet – a critique of the current campaign finance system and special interests that dominate Washington – into something it’s not.

“Only if your mind is in the gutter would you have read” the message as sexual innuendo, she said.

NBC News points out that campaign finance records show Trump donated to Gillibrand’s 2010 special election campaign, as well as her congressional campaign in 2007 and 2008.
