The single-engine aircraft was engulfed in fire after crashing shortly before 11 a.m., Placer County Sheriff’s Lt. Andrew Scott said.

Sheriff investigators were looking into the cause of the crash with the assistance of the National Transportation Board, whose investigators will participate remotely instead of traveling to the crash site due to the COVID-19 pandemic, Scott said.

Kirby gained notoriety last week after social media posts criticizing Trump’s response to the coronavirus pandemic and comparing the president’s supporters to KKK members.
