What did Donald Trump do today?

He resumed his attacks on Hillary Clinton, calling her "guilty as hell" of unspecified crimes.

The Twitter outburst was apparently in reaction to news that the Justice Department would investigate why the FBI briefly, publicly, announced it was reopening its investigation of her on the eve of the election. FBI Director James Comey violated protocol twice during the election with respect to his comments on Clinton's handling of e-mails: first when he editorialized during his announcement that the investigation had turned up no criminal activity, and again when he suddenly and publicly reopened the investigation eleven days before the election. Neither phase found evidence of wrongdoing. 

The Office of the Inspector General, which routinely handles internal investigations of Justice Department agencies, would report on the context of Comey's actions and ensure that no laws were broken as a result. Comey said today that he welcomes the investigation.

Trump may be concerned that any finding that Comey or other FBI agents acted improperly would further undermine the legitimacy of his election in the wake of his popular vote loss and mounting allegations that he colluded with the Russian government to influence the election. 

Who cares?

• A president's political comfort is not as important as the government's ability to ensure that it is following its own rules.
