Preet Bharara, the U.S. Attorney for the Southern District of New York, announced Saturday that he’d been fired by the Trump Administration. Bharara was among the forty-six U.S. Attorneys, all holdovers from the Obama Administration, who were abruptly asked to resign on Friday.

“I did not resign,” Bharara said on Twitter on Saturday afternoon. “Moments ago I was fired. Being the US Attorney in SDNY will forever be the greatest honor of my professional life.”

Bharara has been one of the most prominent prosecutors in the country, going after political corruption in New York State and Wall Street figures. Here are some of The New Yorker’s stories about his career:
