(CNN)Donald Trump lashed out at former presidential candidate Lindsey Graham in the senator's home state of South Carolina Wednesday.

"This guy Lindsey Graham, he's one of the dumbest human beings I have ever seen, " Trump said at a rally in Bluffton. "He starts hitting me, saying vicious things, ends up with 0%. He left in disgrace."
The business mogul also had a direct message to Graham's constituents.
"Lindsey Graham is a disgrace, and I think you have one of the most worst representatives for the state."
Graham, a former Republican presidential candidate, is campaigning for Republican presidential candidate Jeb Bush. Trump and Bush are engaged in a war of words over the Bush family and the Iraq War.
Trump has teased Graham throughout his presidential campaign, most notably last summer when he released Graham's personal cell phone number during a press conference.
CNN has reached out for comment from the Bush campaign and Graham's office.
