Kless mentioned Omar in all three messages, according to police, calling her a “towel head” and member of the Taliban and referencing recent comments she made about the 9/11 terrorist attacks.

The Capitol Police told The Hill it does not comment on ongoing investigations. Details of the allegations were filed in U.S. District Court for the Southern District of Florida and dated Thursday.

"It was your Taliban bitch, the one who opened up her f---ing towel head mouth about how 'some people did it,' " authorities say Kless said in his message to Tlaib, who along with Omar is one of the first two Muslim women elected to Congress.

"You know what? She's lucky she's just getting death threats, bitch. So are you. All right? You're lucky they're just threats. Motherf---er. 'Cuz the day when the bell tolls, whore, and this country comes to a war, there will be no more threats. Your life will be on the f---ing line."

Kless allegedly called Swalwell a communist and said someone would kill him if he enacted the gun control proposals that he has put at the center of his presidential bid.

Authorities also say the suspect repeatedly used racial slurs against Booker and said that he wanted to kill black people, telling him to tell his "colleague with the towel on her head to shut up about 9/11."

Omar has recently been the focus of Republican ire over comments she made in March to the Council on American-Islamic Relations (CAIR), remarks that critics have cited to accuse her of downplaying the 9/11 attacks.

“CAIR was founded after 9/11 because they recognized that some people did something, and that all of us were starting to lose access to our civil liberties,” she said last month.

She later pushed back on those who criticized her for referring to 9/11 as "some people did something," pointing to the larger context of her remarks.

In two of the three voicemails left this week, police say that Kless also defended President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'
