(CNN) Donald Trump's campaign is disavowing the real estate mogul's former butler, after he posted to Facebook Thursday that he wants President Barack Obama to be killed.

Anthony Senecal, who served as Trump's butler for 17 years and now takes groups on tours of the presumptive Republican nominee's Mar-a-Lago estate in Palm Beach, Florida, wrote in a Facebook post Wednesday that Obama "should have been taken out by our military and shot as an enemy agent in his first term," according to Mother Jones, which first reported on Senecal's post

Reached for comment by CNN on Thursday, Senecal, 84, confirmed he wrote the post, but disputed one point, "I think I said hung."

"Either way, I don't care. Hanging, shooting -- I'd prefer he'd be hung from the portico of the White House, or as I call it, the white mosque," Senecal said in a phone interview Thursday.
