WASHINGTON – Donald Trump is considering paying the legal fees for a supporter who sucker-punched a protester in the face at a recent raucous rally, the mogul said Sunday.

“I’ve actually instructed my people to look into it, yes,” the Republican front-runner told “Meet the Press.”

John McGraw, 78, was charged Thursday for punching a black protester, Rakeem Jones, in the face as he was being escorted out of a Trump rally in Fayetteville, NC. Afterwards, McGraw said: “The next time we see him, we might have to kill him.”

Trump has been accused of inciting such violence because he’s encouraged crowds at previous rallies to take out protesters, offered to pay for legal bills for handling problem guests and lamented the “old days” where you could punch a disrupter in the face and he’d be “carried out on a stretcher.”

Marco Rubio said he’s concerned someone might die at a Trump rally.

“He has turned the most important election in a generation into a circus, into a complete fiasco and a carnival. And this country deserves better,” Rubio told “State of the Union.”

“…There are people out there that are unbalanced. There are people out there that do not have control of themselves. We don’t know what they will do.”

“Responsibility starts at the top,” opponent Ted Cruz said of Trump Sunday on “Meet the Press.”

But Trump stood up for his supporters Sunday and blamed Bernie Sanders’ campaign for infiltrating his rallies with aggressive protesters – which Sanders blasted as a lie.

“I don’t accept responsibility, I do not condone violence in any shape,” Trump countered. “From what I saw, the young man stuck his finger up in the air, and the other man sort of just had it.”

Trump said his campaign events have been peaceful and he should be credited with canceling the rally over the weekend in Chicago after protesters were creating a chaotic situation that could have gotten out of hand.

“You haven’t seen one person even injured at one of our rallies,” Trump told “Face the Nation.” “And the cases you are talking about, the one guy was a bad dude. He was swinging, he was hitting people. He was a very bad guy. And the police came in and they really were very effective. And frankly, some of the audience members had no choice but to be effective and I didn’t mind that at all, or they would have been hurt, frankly.”
