The Secret Service said Thursday it was investigating statements made by Donald Trump’s longtime butler Anthony Senecal on Facebook calling for President Obama to be killed.

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

Senecal, who is 74 and now the unofficial historian at Trump’s Mar-a-Lago estate, said in Facebook posts that Obama should be executed. He confirmed to Mother Jones that he authored the posts.

“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 one post on Wednesday, which was visible only to his Facebook friends but was published by Mother Jones. “Instead he still remains in office doing every thing he can to gut the America we all know and love !!!!!”

The Trump campaign responded Thursday, criticizing the comments. “Tony Senecal has not worked at Mar-a-Lago for years, but nevertheless we totally and completely disavow the horrible statements made by him,” a campaign spokesperson said in a statement.

In other posts, Senecal called for a “second American revolution,” reflected Trump’s birther arguments in 2011 and referred to Obama a “Kenyan fraud.”

“Looks like that sleezey bastard zero (O) is trying to out maneuver Congress again, if the truth be known this prick needs to be hung for treason!!!” Senecal said in a Facebook post from April 2015. He claimed Obama is a Muslim and last year, he wrote, “look at the number of goat screwing muzzies he is degrading our government with !!!!!” The butler also said on Facebook there are “to [sic] many fkn muzzies in America” and said Muslims are “invading our country.”

Senecal was Trump’s personal butler for 17 years and closely followed the real estate magnate’s tastes and proclivities. In a New York Times profile, Senecal said Trump likes his steak well-done and does his own hair.

Senecal retired as Trump’s butler in 2009 but he told Mother Jones he continues to give tours at the Mar-a-Lago estate.

A spokeswoman for the Trump campaign told Mother Jones, “This individual has not worked at Mar-a-Lago for many years.”
