Donald Trump said on "The O'Reilly Factor" that there "absolutely" is a bias against conservatives by NBC. 

NBC cut ties with Trump on Monday over his controversial comments about Mexico and illegal immigrants. 

“When Mexico sends its people, they’re not sending their best. […] They’re sending people that have lots of problems, and they’re bringing those problems with us. They’re bringing drugs. They’re bringing crime. They’re rapists. And some, I assume, are good people,” Trump said while announcing his run for president.

O'Reilly asked Trump whether he believes there is an "anti-conservative" bias at the network.

"You absolutely have a tremendous bias," said Trump.

Trump said NBC is "angry" at him because he's running for president, highlighting that "The Apprentice" was an "amazing success."

He said the reasons behind NBC's decision "will come out in litigation."

Trump said he stands by his original comments about Mexico, because they are "totally accurate."

"The border is a disaster Bill," Trump said. "People are pouring in, and I mean ... illegal immigrants 300 and some odd thousand are in your state jails right now according to Homeland Security ... This is an amazing statistic, 80 percent of Central American women and girls are raped crossing into the U.S."

He noted that both Fusion and Huffington Post published stories about that statistic. 

"I love Mexican people," Trump said. "I have a tremendous relationship, I also respect Mexico. But Mexico is doing a tremendous number against the United States. First of all they're killing us at the border. Second of all, Bill what they're doing to us in trade is unbelievable."
