ROCHESTER, N.Y. (AP) — A western New York man pleaded guilty Monday to threatening to kill U.S. Rep. Ilhan Omar of Minnesota.

Patrick Carlineo entered the plea Monday in Rochester, admitting to charges that carry up to 10 years in prison. His sentencing is set for Feb. 14.

U.S. Attorney James Kennedy Jr. said the case highlights that free speech rights carry the responsibility “that individuals not make threats to harm lawmakers simply because they may disagree with them.”

Omar, a Democrat, is among the first Muslim women in Congress. Her office had no immediate comment on Carlineo’s plea.

Prosecutors say the 55-year-old called Omar’s office March 21, told a staffer the congresswoman was a “terrorist” and threatened to shoot her.

Carlineo later told the FBI that he is a patriot, hates people he perceives to be radical Muslims in the U.S. government, and loves Republican President Donald Trump, according to a criminal complaint.
