President Donald Trump didn’t just regularly torture and demean former White House press secretary Sean Spicer — he did the same to his former chief of staff, Reince Priebus, The Washington Post reports.

“At one point, during a meeting in the Oval Office, a fly began buzzing overhead, distracting the president,” reports The Post. “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 demeaning treatment played a role in Priebus leaving.

“Allies to Priebus said he told them he had resigned because the internal chaos had become ‘unsustainable,’ and that he felt demeaned by the president’s treatment of him,” said the report.

The Post cites two sources in reporting that Trump first offered the job to Kelly in mid-May, but kept on Priebus when Kelly declined. So Trump continued to woo him.

“The president has tried to convince the general multiple times, and the general has politely declined several times,” an anonymous source told The Post.

President Trump wasn’t the only one to bully the top staffer in the White House.

“Priebus’ final departure was a humiliating coda for what had been a largely demeaning tenure during which he endured regular belittling from rival advisers — and even, at times, the president himself,” The Post reports. “His exit was described by one Republican strategist as ‘the red wedding,’ a reference to a mass-murder blood bath episode of HBO’s ‘Game of Thrones.'”
