"I don't know what's going to happen," he said on ABC's "This Week."
Trump sparked criticism last week when he predicted riots if he doesn't win the nomination, given his lead among delegates.
"I think you'd have riots," Trump said. "I'm representing ... many, many millions of people, in many cases first-time voters."
Trump said on Sunday that although he doesn't want to see riots, he can't say how his supporters will respond if he doesn't secure the nomination.
"If the Republicans embraced these great people that are showing up, the Republicans are going to have a massive victory. It's not going to be a Mitt Romney slaughter, because he was such a bad candidate.
"The Republicans are going to have a massive victory in November."
Trump also on Sunday defended his campaign manager, Corey Lewandowski, who came under fire again this weekend after appearing to grab a protester by the collar and pull him back during a rally in Tucson, Ariz.
"I give him credit for having spirit. He wanted them to take down those horrible, profanity-laced signs," Trump said on ABC. "The police were a little bit lax, and he had signs. They had signs up in that arena that were horrendous."
Lewandowski had previously been accused of grabbing the arm of former Breitbart reporter Michelle Fields and yanking her down. The Trump campaign also denied that claim.
After being asked about violence at his rallies this past weekend, Trump called on some of the blame to be put on the protesters.
"At what point do people blame the protesters?" he asked.
This past weekend, protesters blocked traffic to a Trump rally in Arizona by parking their cars near the location. The protest delayed the rally by an hour, Trump said. Another protester was punched and kicked several times as he was being taken out of the rally.
"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.
He added that some protesters have signs with "tremendous profanity" on them.
"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."
He called it "unfair" that "professional" and "sick" protesters can act in this way and "nobody says anything about that."
A series of violent events have occurred at Trump's campaign events recently. Earlier this month, a Trump supporter punched a protester in the face as he was being led out of a North Carolina rally. The front-runner canceled a rally in Chicago amid massive protests.
Still, Trump said on Sunday that there has not been much violence at his events.
"We don't condone violence, and I say it," he said.
"And we have very little violence — very, very little violence at the rallies."
