Los Angeles Mayor Karen Bass fired Kristin Crowley, the city’s fire chief, on Friday over her handling of last month’s wildfires. She praised Crowley’s leadership on the matter in January.

The firing is effective immediately, according to a press release, and among the reasons cited for Crowley’s removal was the sending home of 1,000 firefighters on the morning the fires broke out, as well as her alleged refusal to conduct an after-action report.
