Donald Trump’s longtime butler Anthony Senecal said that President Obama is a “sleazy bastard” who should be “should be hung for treason.”

Seneca, who worked as Trump’s butler for 17 years before being named the in-house historian at the business mogul’s Mar-a-Lago estate in Palm Beach, has posted series of rants about the current president on his Facebook page over the past year, calling him “against the people of America” and “a rotten filthy m—-ie,” a racial slur for Muslims used by white nationalists.
