Meghan McCain and Brian Kilmeade weighed in on "Outnumbered" following Tuesday night's wild scene in the U.S. Senate, where Elizabeth Warren was blocked from reading a 1986 letter by Corretta Scott King.

The liberal Massachusetts Democrat was attempting to recite the words of Martin Luther King's widow, which criticized Sen. Jeff Sessions' record on civil rights. 

Democrats were staging another overnight debate to delay a vote on Sessions' nomination to be attorney general. Warren was reminded that reading the letter was a violation of Senate rules.

The Senate then rebuked Warren in a party-line vote. Senate Minority Leader Chuck Schumer (D-NY) criticized Republicans for "selective enforcement" of the rule. 

Warren quickly took to Twitter, where the topic was trending and liberal critics were accusing Republicans of sexism.

Kilmeade said it was a "big act" by Senate Democrats, who are attempting to raise money off of the all-night remarks. He also noted Warren only has a 44 percent approval rating in her home state. 

McCain called it "political theater at its very worst" and said for Warren, it's all about setting herself up for a 2020 presidential run. 

"She wants to be, sort of, the next Hillary Clinton if you will, except more extreme. This is all about politics, hashtags on Twitter and being on television. This is not about Jeff Sessions," she argued, adding that Democrats are going to continue the "tantrums" on each Trump nominee. 

McCain said the Democrats' strategy of trying to paint Trump and Republicans as racists will backfire in 2020.
