Fox News anchor Bill O’Reilly took on GOP frontrunner Donald Trump about his recent outlandish tweets regarding alleged national statistics on Black-on-white homicides.

The stats weren’t backed by any official sources and were considered by most to be nothing more than racially stereotypical propaganda.

“You tweeted out that whites killed by Blacks — these were statistics that you picked up from somewhere, at a rate of 81 percent and that’s totally wrong. Um. Whites killed by Blacks is 15 percent, yet you tweeted it was 81 percent” O’Reilly said.

Trump, who referred to himself as the “least racist person on earth,” defended himself by stating he didn’t tweet it, he simply “retweeted somebody that was supposedly an expert.” Trump then questioned whether he was supposed to “check every statistic?” to which O’Reilly replied, “You gotta. You’re a presidential contender. You gotta check it…”.

Bill O’Reilly then offered the Republican candidate some much-needed advice: “Don’t do this. Don’t put your name on stuff like this ’cause it makes the other side, it gives them stuff to tell the ill-informed voter that you’re a racist.”
