Trump, according to several people with knowledge of the discussions, was upset that Gorsuch had pointedly distanced himself from the president in a private February meeting with Sen. Richard Blumenthal (D-Conn.), telling the senator he found Trump’s repeated attacks on the federal judiciary “disheartening” and “demoralizing.”

The president worried that Gorsuch would not be “loyal,” one of the people said, and told aides that he was tempted to pull Gorsuch’s nomination — and that he knew plenty of other judges who would want the job…

Trump was especially upset by what he viewed as Gorsuch’s insufficient gratitude for a lifetime appointment to the nation’s highest court, White House officials said. The judge sent the president a handwritten letter dated March 2, thanking him for the nomination and explaining how grateful he was, according to a copy obtained by The Washington Post.
