He also unleashed his anger online Tuesday, tweeting, “Attorney–client privilege is dead!” and “A TOTAL WITCH HUNT!!!”
Sanders has said in the past that “the president has the right … but no intention” to fire Mueller.
Technically, only the deputy attorney general who appointed Mueller can fire him and only for cause. Currently, that person is Rod Rosenstein. However, Trump could fire Rosenstein, or order the special counsel regulations repealed and fire Mueller himself.
A person with knowledge of the matter told NBC News that Rosenstein directly approved the application for a search warrant for Cohen.
