Patrick W. Carlineo Jr., of Addison, New York, may face 10 years in prison or a $250,000 fine, or both, U.S. Attorney James P. Kennedy Jr. said in a statement on Friday. Assistant U.S. Attorney Brett A. Harvey is handling the case.
The arrest stems from a March 21 phone call received by one of Omar's staffers in which a man later identified as Carlineo allegedly said, "Do you work for the Muslim Brotherhood? Why are you working for her, she's a [expletive] terrorist. I’ll put a bullet in her [expletive] skull.”
The threatening call was referred to Capitol Police, who investigated in coordination with the FBI.
Carlineo appeared in court on Friday and is being held pending a detention hearing on April 10, according to a statement from the Justice Department.
Authorities didn't say when Carlineo was apprehended, according to The Associated Press, to which the suspect's attorney declined to comment.
