Trump denies NYT report on firing Mueller in angry morning tweet -- but also threatens to do it

President Donald Trump denied a New York Times report but confirmed its premise in an angry morning tweet.

The president logged into Twitter on Thursday morning to refute a Tuesday night report that he sought to fire special counsel Robert Mueller in December.

"If I wanted to fire Robert Mueller in December, as reported by the Failing New York Times, I would have fired him," the president tweeted. "Just more Fake News from a biased newspaper!"

Republicans have said firing Mueller could trigger serious consequences, but they have refused to pass any legislative measures to protect the special counsel.
