"At the end of the day in any campaign, responsibility starts at the top," the Texas senator said on NBC's "Meet the Press" on Sunday.
Cruz said on Sunday that the protesters at Trump's rallies don't have a right to "threaten violence."
He added that it's important a candidate show respect for the voters. He said he's been "troubled" by the rallies Trump holds, noting the pledge Trump asks people to take at some of his rallies to support him.
Cruz said protests at his events are "very different."
"When I have protesters at my events, I endeavor to engage them with civility and respect. More than once, I've actually had a conversation with the protesters on substance," he said.
Protesters who are just "shouting and disrupting," he said, will be removed, but Cruz said he is open to having discussions with protesters, touting himself as a candidate who "is showing the voters respect."
