Trump's chief of staff gets stopped in his tracks: No, you're wrong...on everything (VIDEO)

White House Chief of Staff Mick Mulvaney appeared on Fox News to discuss President Donald Trump's bitter Twitter feud with Rep. Elijah Cummings, Mueller's testimony on Capitol Hill, and the new budget cap.

Things got particularly heated when host Chris Wallace suggested Trump was aiming below the belt by his comments, and was doing so mainly because of race stereotypes.

"You say it doesn't have to do anything with race but there is a clear pattern here. The fact is before his inauguration, Trump tweeted about a black congressman, John Lewis, that he should spend time in his crime-infested district. Then - two weeks ago he goes after the four women of the squad, all women of color, and says they should go back to their crime-infested countries."

Chris Wallace: "Infested. It sounds like vermin. It sounds subhuman and these are all six members of Congress who are people of color."  

Mulvaney says he's "spending too much time reading between the lines."

Wallace: "I'm not reading between the lines. I'm reading the lines."

On the topic of Robert Mueller, Mulvaney was hoping for some more success, but that too proved to be a failure for him on the show.

Mulvaney: Mueller answered the biggest question. He said he wouldn't have indicted the president, if he wasn't president, and Mueller said absolutely not.

Chris Wallace: That's not what he said. He said he couldn't make a decision on indictment b/c of OLC opinion.  

Mulvaney: I just think you're wrong.  

Chris Wallace: I promise you you're wrong.
