An outspoken Manhattan federal prosecutor known for crusading against public corruption says he was fired after refusing to resign. Preet Bharara announced in a tweet Saturday afternoon that he was fired.

He said: “I did not resign. Moments ago I was fired.” He went on to say in the tweet that being the US Attorney in the Southern District of New York will “forever be the greatest honor of my professional life.”

Bharara was asked by then-President-Elect President Donald Trump to remain as U.S. attorney in Manhattan during a November meeting. The Justice Department confirmed Bharara was no longer U.S. attorney but declined further comment.

The 48-year-old Bharara must leave the post after unveiling dozens of insider trading cases and successfully prosecuting over a dozen state lawmakers, Democrats and Republicans alike.

Bharara was appointed by former President Barack Obama in 2009. In frequent public appearances, Bharara has decried public corruption after successfully prosecuting over a dozen state lawmakers, Democrats and Republicans alike.

Michigan Rep. John Conyers, the House Judiciary Committee’s top Democrat, wants a summary of probes linked to President Donald Trump in light of the dismissal of dozens of federal prosecutors. Conyers says in a release that Saturday’s firing of Manhattan U.S. Attorney Preet Bharara is a particular problem.

Conyers says he wants the Justice Department to reveal to the judiciary committee all probes touching on the Trump administration, transition, campaign and organization.

New York’s attorney general says the sudden dismissal of dozens of U.S. attorneys nationwide has caused chaos in the federal government, but legal observers say it’s not unusual.

He says Bharara could be reviewing a range of potential improper activity involving Trump Tower and the campaign of President Donald Trump.

Conyers notes that Attorney General Jeff Sessions, who sought the resignations Friday, has been at the center of his own scandal. Sessions’ confirmation hearing testimony has been criticized as inaccurate.
