"These are professional agitators, and I think that somebody should say that when a road is blocked going into the event so that people have to wait sometimes hours to get in, I think that's very fair and there should be blame there, too," he said on ABC's "This Week."
"I mean the worst profanity, and you have television cameras all over the place and people see these signs," he said.
"I think maybe those people have some blame and should suffer some blame also."
At a rally in Arizona on Saturday, protesters parked their cars near the location to block traffic. Traffic was backed up for miles, CNN reported.
Trump called it "unfair" that "professional" and "sick" protesters could put their cars in the road and block thousands of people from coming to his speech. He said the rally was delayed for an hour because of the protesters.
"And nobody says anything about that," he said.
He also defended his rallies, saying he has huge numbers of people come out with few incidents. He added he does not condone violence.
"And we have very little violence — very, very little violence at the rallies," he said.
