White House press secretary Sarah Sanders said Wednesday that leakers in the White House should be fired.

“I can’t answer why people do it because I don’t engage in [leaking],” Sanders told Fox News Wednesday morning. “I find it to be some of the most disgusting behavior that you could ever participate in, and one of the most disloyal things that you could do as an entrusted member of the president's team.”

“It’s an honor and a privilege to work for the president and to be part of his administration. And anybody who betrays that, I think is a total and complete coward and they should be fired,” Sanders said. “We fired people over leaking before. I have personally fired people over leaking before. And we certainly would be very willing to do so again.”

The White House has been under fire for a comment White House aide Kelly Sadler made about how it doesn't matter how Sen. John McCain, R-Ariz., votes now because "he's dying anyway."

But Sanders and others in the White House have indicated there will be no public apology for that comment, and instead have focused on the leak instead of the substance of the remark. Sanders told Fox she doesn't want to "validate" the comment and again argued that the press needs to spend more time on the progress President Trump is making on the economy and foreign affairs.
