The U.S. Secret Service paid a visit to the Florida state House candidate who advocated for President Barack Obama’s execution on Twitter.

Joshua Black, a Republican who is running in Florida House District 68, told the Tampa Bay Times that Secret Service agents had come to his home following the uproar over his comments.

“I’m past impeachment. It’s time to arrest him and hang him high,” read a message on Black’s campaign Twitter page Monday.

“It was not a threat,” Black told the Times, asserting that the comments were a response to Obama ordering drone strikes that had killed Americans.

Florida Gov. Rick Scott (R) also called on Black to withdraw his candidacy.
