Then again, if Bharara were to resign, President Trump and Attorney General Sessions could refuse to accept it - and refuse to accept the resignations submitted by other selected U.S. Attorneys.

Because it is not unusual for a new President to request the resignations of all U.S. Attorneys who were appointed by previous administrations (especially where a new party has taken office), who is in a position to say that it is inappropriate for Trump to ask that ALL attorneys resign - even those whom the President wishes to retain? To criticize the Trump administration - which CNN and other media outlets are doing - is short-sighted at best, or biased at worst. 

That said, U.S. Attorney Preet Bharara, who is the prosecutor for the Southern District of New York, will apparently refuse to submit his resignation. That could set up a showdown on Monday with the Justice Department. White House and DOJ officials have not yet commented on how, if at all, they will handle Mr. Bharara and any other federal prosecutor who refuses to resign.

The Southern District covers Manhattan, the Bronx, Westchester and other counties north of New York City. The Eastern District of New York covers Brooklyn, Queens, Staten Island and Long Island.
