All the subpoenas
By 
Trump — with the collaboration of his consigliere Bill Barr — is simply refusing to comply with valid subpoenas, on the novel grounds that the Democratic Party intends to compete in the 2020 elections:
The Trump administration escalated its defiance of Congress on Wednesday, as the Justice Department refused to let an official testify on Capitol Hill and President Trump vowed to fight what he called a “ridiculous” subpoena ordering a former top aide to appear before lawmakers.
“We’re fighting all the subpoenas,” Mr. Trump told reporters outside the White House. “These aren’t, like, impartial people. The Democrats are trying to win 2020.”
The moves added to an already remarkable week of stonewalling by the Trump administration after the release of the report by the special counsel, Robert S. Mueller III, that revealed the scope of the Russian operation to help Mr. Trump win the 2016 election and detailed his attempts to impede an investigation he saw as imperiling his presidency.
Time for another round of complacent essays about how concerns about Trump’s authoritarianism are overblown!
Attorney General Jeff Sessions had a tenuous hold on his job when President Trump called him at home in the middle of 2017. The president had already blamed him for recusing himself from investigations related to the 2016 election, sought his resignation and belittled him in private and on Twitter.
Now, Mr. Trump had another demand: He wanted Mr. Sessions to reverse his recusal and order the prosecution of Hillary Clinton.
