WashPost lead story, by Philip Rucker, Abby Phillip, Robert Costa and Ashley Parker:
"Trump had long questioned the depth of Priebus' loyalty, often remarking about how ... Priebus encouraged Trump to drop out of the presidential race after [the 'Access Hollywood' tape]. The senior official described Priebus' counsel that day as 'a stain he was never going to remove. The scarlet 'A.H.'"
"Trump's demeaning of Priebus came through in other ways, too. At one point, during a meeting in the Oval Office, a fly began buzzing overhead, distracting the president. As the fly continued to circle, Trump summoned his chief of staff and tasked him with killing the insect, according to someone familiar with the incident. (The West Wing has a regular fly problem.)"
