From the New York Times:

“Deputy Attorney General Rod J. Rosenstein adamantly defended the character and impartiality of Robert S. Mueller III, the special counsel, as he came head-to-head on Wednesday with an increasingly aggressive campaign by Republicans to discredit the inquiry…

“…the swelling campaign to undermine Mr. Mueller’s investigation, which has dominated conservative media for days, appeared to have little effect on Mr. Rosenstein, who oversees Mr. Mueller. Mr. Rosenstein said he would only fire Mr. Mueller if he had cause under Justice Department regulations — and he said nothing that has happened so far met that standard.

“Mr. Rosenstein’s stance signaled that despite the mounting assault on Mr. Mueller by Mr. Trump’s supporters, the fundamental dynamic surrounding the special counsel had not changed: If Mr. Trump were to try to fire Mr. Mueller based on any developments so far, the president would likely first have to fire or force the resignation of Mr. Rosenstein and then hunt for a replacement willing to carry out his orders, echoing Richard Nixon’s so-called Saturday Night Massacre during the Watergate scandal.
