In his latest attack on the Russia investigation, President Donald Trump tweeted, “The appointment of the Special Counsel is totally UNCONSTITUTIONAL!” This amounts to Trump’s opinion, and is a matter of debate among constitutional scholars.
Q:Can President Donald Trump fire special counsel Robert Mueller?
A:Not directly. Only the deputy attorney general who appointed Mueller can fire him and only for cause. But Trump could fire the DAG, or order the special-counsel regulations repealed and fire Mueller himself.
