John Kless, 49, of Tamarac, Florida was arrested on Friday and appeared before a magistrate judge in the Southern District of Florida, charged with making threatening communications.
Kless is suspected of recording threatening messages on Tuesday on the phones of US Senator Cory Booker, US Representative Rashida Tlaib and US Representative Eric Swalwell, according to a criminal complaint filed by prosecutors, Presstv Reported.
The suspect also used racist and abusive language at Omar without naming her.
The caller referred to recent comments by Omar about the attacks of September 11, 2001, that Trump and other conservatives have described as minimizing the 9/11 attack.
Omar was condemning the repression against Muslims in the United States following the attacks when she referred to 9/11 as “some people did something.”
Another man from the state of New York was arrested earlier this month for threatening to murder Omar.
The arrests come amid other incidents of racial tension in the United States and a more extreme political discourse.
