Univision reporter Jorge Ramos was kicked out of a Donald Trump event Tuesday in Dubuque, Iowa, which was followed by a testy exchange over illegal immigration that put the Republican candidate's famously combative nature on full display.

Ramos was forcibly removed by security early in the press conference after he tried to ask Trump a question even though he apparently had not been called on. The move hit a nerve with the Republican candidate, who repeatedly told him to sit back down even as Ramos insisted on asking the question. "I have the right to ask a question," Ramos said.

"No you don't," Trump said. "Go back to Univision."

With Ramos outside, another reporter brought the exchange back up with Trump, which prompted the candidate to dig the Univision reporter.

"He's obviously a very emotional person," Trump said about Ramos.

However, Ramos was not gone for long. He was allowed to return minutes later, to which Trump responded, "Good to have you back."

This time, Trump permitted Ramos to ask his question, but their spat was not over. The Univision reporter proceeded to ask the real estate mogul about illegal immigration.

"We're going to do it in a very human fashion," Trump told Ramos. "I have a bigger heart than you."

Trump defended his firm position to deport illegal immigrants, saying that he's "looked at some of the gangs" and they're made up of them. "Do you mind if I send them back to Mexico?" said Trump. "They'll be out so fast your head will spin."

Ramos challenged Trump and his use of the term "illegal immigrant."

"No human is illegal," he said.

Ultimately, Trump dismissed Ramos' questions. "I can't deal with this," Trump said and turned his attention to another reporter.

Trump has been at odds with Univision after the Spanish-language TV networked decided not to air his Miss USA and Miss Universe beauty pageants after Trump's remarks about Mexican immigrants during his campaign announcement June 16. In response, Trump is reportedly suing the network for $500 million.
