What did Donald Trump do today?

He celebrated the chance to appoint an FBI director he thinks will be personally loyal to him… again.

Shortly after taking office in 2017, Trump demanded that then-FBI Director James Comey swear personal loyalty to him. Comey refused, and Trump fired him shortly thereafter. 

The firing was particularly urgent for Trump, because the FBI was conducting the investigation into Russia's interference on Trump's behalf in the 2016 election. In fact, the firing was so suspicious that the acting FBI Director immediately opened an obstruction of justice investigation into Trump. As a result, Deputy Attorney General Rod Rosenstein appointed Robert Mueller as a special counsel to investigate exactly how much influence Russia had over the election—and over Trump.

This was the sequence of events that led to Trump appointing Christopher Wray as the new FBI Director in 2017. Wray remained in office through the end of Trump's term, earning some respect for his willingness to defend the nation's law enforcement agencies from Trump's attacks.

After Trump left office, he was indicted in federal court for stealing classified documents and fomenting a coup. The FBI was involved in investigating both sets of crimes and, among other things, executed search warrants on Mar-a-Lago, where Trump had stashed those boxes of stolen government documents.

Trump was infuriated by Wray's "disloyalty" in refusing to obstruct those investigations, and promised to replace him if re-elected. Today, after Wray's announcement that he would resign rather than be fired, Trump was gleeful, saying that "today is a great day for America as it will end the Weaponization of what has become known as the United States Department of Injustice." 

Trump plans to replace Wray with another director he hopes will be personally loyal to him—and he may get it this time. Kash Patel is an election denier who has mimicked Trump's language about the supposed "deep state" conspiracy against him and—again parroting Trump—threatened to jail journalists.

Why does this matter?

• It is under no circumstances whatsoever appropriate for a president to demand a pledge of personal loyalty from the director of the FBI.

• Even now, nobody is above the law, but it's bad if Trump thinks he is and acts like it.

• Virtually all of the people Trump accuses of "weaponizing" politics against him are Republicans he appointed.
