Anthony Senecal worked as Trump's butler for 17 years and then became an unofficial historian at Trump's Mar-a-Lago estate in Palm Beach, Fla., according to The New York Times. Senecal reportedly tried to retire in 2009, but Trump told him that "to retire is to expire" and said he would see him next season.

On Wednesday, Senecal wrote in a Facebook post that Obama should be shot by the military as an "enemy agent."

"To all my friends on FB, just a short note to you on our pus headed 'president' !!!! This character who I refer to as zero (0) should have been taken out by our military and shot as an enemy agent in his first term !!!!!" Senecal said in a Facebook post, according to Mother Jones.

"Instead he still remains in office doing every thing he can to gut the America we all know and love !!!!!"

It was not the first time Senecal called for Obama's death in a Facebook post.

The Secret Service said Thursday it will investigate the comments.

“The U.S. Secret Service is aware of this matter and will conduct the appropriate investigation,” agency spokesman Robert Hoback said in a statement.
