"In the aftermath of this incident, I was accused of being an activist," Ramos wrote in an online post Wednesday. "That's not the case — I'm simply a journalist who asks questions. And journalists have an obligation to take a stand when it comes to racism, discrimination, corruption, public lies, dictatorships and human rights violations."

Jorge Ramos appeared on Fox News' "The O'Reilly Factor" Wednesday, responding to accusations that he has become an activist and is not a journalist.

Ramos is one of the most trusted news source among American Latinos, and when he appeared on Fox News' "The O'Reilly Factor" on Wednesday, he said he was simply doing his job when he confronted Trump.

"I think what Donald Trump is doing is very dangerous. He's proposing the largest mass deportation in recent history," Ramos said to O'Reilly in what quickly devolved into an on-air shouting match. "Who's going to challenge him? That's our job as reporters."

"How can you possibly cover illegal immigration when you're an activist .… You should excuse yourself from it … or become like me, a commentator," O'Reilly said.
