But what Comey did isn't really what's at issue. The Constitution says Comey, like all FBI directors, is something like an "at will" employee.
Yes, there is a federal statute that provides that the director has a 10-year term, but that provision does not constrain the president's firing power, it merely limits his or her ability to keep a valued or friendly director in office after the expiration of the term. (No director can serve more than 10 years without some further legal action by the president, the Senate or Congress.)
That’s how the provision’s chief congressional sponsor, Sen.
Byrd's understanding, and the Court of Appeals', is based on the constitutional principle, derived from Article II, Section 1, that the president supervises the executive branch of the government. During a debate in the 1st Congress, James Madison expressed the view that the Constitution mandated that "the first Magistrate should be responsible for the Executive department" and, by implication, that it limits Congress's authority "to diminish or modify" such authority. Later Supreme Court cases have upheld some statutes that constrain the president's firing authority (such statutes typically require "cause" for removal), but absent such constraints, officers in the executive branch serve at the president's pleasure.
The president's power in this regard is not a mere legal technicality but rather a central part of our constitutional framework. Every four years, the nation elects a chief executive, based on his or her platform, which may include promises about how the executive branch will direct its limited law enforcement resources. Those elections and promises would be a meaningless charade if an incoming president could not remove subordinates who refused to carry out the platform chosen by the people.
All that said, whatever legal discretion the president enjoys, a prudent president should remove an FBI director only for legitimate reasons. The backlash for politicizing law enforcement, or even appearing to politicize it, can be devastating. Witness the outcry and criminal investigation that arose when the George W. Bush administration removed sitting U.S. attorneys, allegedly because they pursued or failed to pursue prosecutions that met the president's political agenda. President Nixon's "Saturday night massacre," in which he dismissed Watergate special prosecutor Archibald Cox, provoked similar outrage. A controversial removal of an FBI director now would prompt howls and feverish conspiracy theories.
Has Comey made decisions that warrant his dismissal? It is not for us to say, especially as neither we nor the rest of the public have all the facts. Still, based on the statements of Clinton and her supporters, it would appear that, should she be elected, his dismissal could be imminent.
On the other hand, the White House press secretary seemed to indicate that President Obama didn't agree: "The president is completely confident that Director Comey has not taken any steps to try to intentionally influence the outcome of the election or to advantage one political party," Josh Earnest said Monday.
If a newly installed President Clinton does remove Comey, she would be repeating history. About six months after his inauguration, President Bill Clinton concluded that then-FBI Director William S. Sessions had committed a number of ethical violations. The outgoing attorney general under the George H.W. Bush administration had accused Sessions of such lapses as taking personal trips on the FBI plane and using government money to build a security fence at his house. Bill Clinton judged that Sessions could not effectively lead the bureau.
Although the administration pushed Sessions to resign, when he didn't and was removed, there was no significant outcry about the politicization of the FBI, which reflected an acknowledgement that the law gives the president removal authority over subordinate executive branch officers. It is a central, not incidental, constitutional principle.
