What did Donald Trump do today?

He once again claimed that he was personally "betrayed" by Jefferson Sessions' recusal from the Russia investigation.

Last month, after Trump offered Joe DiGenova a spot on his legal defense team, the Fox News lawyer shied away, citing conflicts with current clients. But he has continued to provide political cover for Trump, who quoted him in a tweet today: "The recusal of Jeff Sessions was an unforced betrayal of the President of the United States.”

Sessions was a senior figure in the Trump campaign, and secretly met at least twice with Russia's then-ambassador, Sergey Kislyak--though he denied any such meetings during his confirmation hearings. Because this makes him at the very least a witness to the matters under investigation, he recused himself on the strenuous advice of other DOJ lawyers.

Trump seems completely unshakeable in his belief that the Attorney General (and the whole Department of Justice) serves the legal interests of the president personally. He has often spoken favorably of President Obama's attorney general, Eric Holder, praising him for what Trump thinks was his "protection" of Obama from criminal liability. 

Holder has responded by pointing out, correctly, that the Department of Justice serves the rule of law, not the president.

So what?

• The president is not above the law.

• The president does not get special protection from the law.

• When presidents try to make their attorneys general serve them, and not the country, it doesn't end well for either.
