Anthony Senecal, who worked as Donald Trump’s butler for 17 years, has expressed hatred for President Barack Obama and declared he should be killed.

He worked as a butler, before being made the in-house historian at the tycoon’s Mar-a-Lago estate in Palm Beach. It has been reported that Senecal had published repeated posts on his Facebook page.

Senecal now takes groups on tours of the presumptive Republican nominee Donald Trump’s Mar-a-Lago estate in Palm Beach, Florida.

In a Facebook post he made on Wednesday, Senecal wrote that Obama should have been “taken out by our military.” He also said that as Obama is an enemy agent, he should have been shot dead during his first term.

However, Donald Trump’s campaign disavowed the “horrible statements.” In a statement made on Thursday afternoon, Hope Hicks, Trump’s campaign spokesperson, denounced the statement.

He said that Senecal has not been working at Mar-a-Lago for years.  Even after that the campaign entirely and completely disavowed the terrible statements made by him about the President, says Mother Jones.

When asked, Senecal confirmed that those were his words. He said that he wrote them and that he believes in them.

But the 84-year-old butler disputed his statement at one point. “I think I said hung,” he said.

“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 an interview on Thursday.

He also added that it would sound like he is insane but he is not. According to CNN, Senecal said that he has just got fed up with Obama.

From a far-right perspective, he looks down upon Obama and his wife, along with Hillary Clinton, other Democrats and Republican leaders. While referring to Obama as “zero,” he has called for the president’s execution, several times.
