The Washington Post has an in-depth article on l’affaire Comey: Inside Trump’s anger and impatience — and his sudden decision to fire Comey.
It’s a long article, so allow me to present just two short teasers on this (emphases mine):
But the private accounts of more than 30 officials at the White House, the Justice Department, the FBI and on Capitol Hill, as well as Trump confidants and other senior Republicans, paint a conflicting narrative centered on the president’s brewing personal animus toward Comey. Many of those interviewed spoke on the condition of anonymity in order to candidly discuss internal deliberations.
Seriously? More than 30?
At his golf course in Bedminster, N.J., Trump groused over Comey’s latest congressional testimony, which he thought was “strange,” and grew impatient with what he viewed as his sanctimony, according to White House officials. Comey, Trump figured, was using the Russia probe to become a martyr.
And guess what you just did, Donald!
