Federal authorities have charged a Cleveland man with sending a Twitter message saying he wanted to assassinate President-elect Donald Trump, investigators said

“My life goal is to assassinate Trump. Don’t care if I serve infinite sentences. That man deserves to decease (sic) existing,” Zachary Benson, 24, tweeted on Nov. 9, according to authorities. The threatening words were among several other posts he sent that promoted violence, officials said.

When Benson later realized that he “went too far,” he deleted the tweets, but it was too late. The Secret Service had already been notified, officials said.

Benson told investigators he “never had any intentions behind any of the posts” but was “frustrated” when he thought how the Trump administration’s policies might affect his job. That job was not disclosed.

Benson is being held on $20,000 bail and faces up to five years in prison if convicted.
