Sonmez was highly critical of Weigel for the tweet, prompting Washington Post Executive Editor Sally Buzbee to put out a memo encouraging staff members to treat one another with respect and kindness, including on social media platforms, and reminding staff that criticizing fellow employees was a violation of company policies.

“We do not tolerate colleagues attacking colleagues either face to face or online,” the paper’s top editor said in a memo on Tuesday.

But the infighting continued from there. Another Post reporter, Jose A. Del Real, accused Sonmez of trying to publicly bully Weigel over a mistake for which he had apologized. Sonmez responded in kind: “When women stand up for themselves, some people respond with even more vitriol.”

Sonmez continued to rail against the paper’s leadership from there, with lengthy threads arguing that it had done little to create an inclusive culture or protect reporters from internal and external harassment. The New York Times reported on Thursday that in its termination letter to Sonmez, Post leadership wrote that her conduct amounted to “insubordination, maligning your co-workers online and violating The Post’s standards on workplace collegiality and inclusivity.” POLITICO has not been able to authenticate the letter.

The week-long episode was an extension of years of grievances she has publicly aired. Last year, Sonmez filed a lawsuit against the paper after it prohibited her from covering stories related to sexual assault and misconduct, citing her previous high-profile statements condemning harassment and mistreatment. The suit was dismissed by a D.C. judge earlier this year, saying Sonmez had not proved that the Post showed a “discriminatory motive.”
