According to The Daily Caller:

The FBI, U.S. Secret Service, and U.S. Marshals are currently searching for a man who is accused of making threats to assassinate President Trump.

Shawn Richard Christy, 27, from McAdoo, Pennsylvania was last seen Sunday night in a stolen vehicle in Cumberland, Maryland, according to CNN.

According to officials, Christy posted on Facebook, "Keep it up [Northampton County District Attorney John] Morganelli, I promise I'll put a bullet in your head as soon as I put one in the head of President Donald J. Trump."

He also said he would use "full lethal force on any law enforcement officer that tries to detain me" on Facebook.
