Man Heckles Trump While Wearing Shirt with Violent Message

A man who interrupted President Trump's speech at Darline Graham's South Carolina rally Friday was booted from the event ... while wearing a shirt that encouraged people to murder their "local pedophile."

Check it out -- the unnamed man began yelling while Trump praised Graham at the Myrtle Beach Convention Center and was swiftly escorted out of the venue. It's unclear what he said out loud, but his shirt made an enormous statement, as it read ... "KILL YOUR LOCAL PEDOPHILE."

The prez was elated to see the man exiting the room, taunting him by saying ... "That’s all right. That person’s going home to mom. Gonna get scolded because mom is voting for us. You know, mom is voting for us."

We reached out to the Myrtle Beach Police ... who confirmed the heckler was not arrested.

We told you about Trump's trip to the oceanfront town -- specifically the fact that his aide Natalie Harp was by his side not long after alleged intimate notes she sent to him were published.

Natalie's notes, in large, were very apologetic to Trump for some mistakes she had made ... and she told him she wanted "things to always be right between" the two.

The head-turning notes came just days after her brother, Preston, said she had "an unhealthy obsession" with Trump.
