Donald Trump met with U.S. Attorney Preet Bharara on Wednesday at Trump Tower, a senior law enforcement official told NBC News.



Bharara, whom many regard as the Justice Department's most powerful prosecutor, told reporters that he agreed to remain the U.S. attorney in the Southern District of New York after a "good meeting" with the president-elect. He added that Sen. Jeff Sessions, Trump's attorney general pick, previously reached out to him, asking him to stay as well.

Bharara and his office are known for their successful prosecutions of Wall Street figures, such as securing the guilty plea of Bernie Madoff's brother, Peter, for his role in the infamous Ponzi scheme.

The federal prosecutor also created two units focusing on financial fraud, including the Civil Frauds Unit, which has collected multimillion dollar settlements from financial institutions.

Bharara also successfully prosecuted two top New York state lawmakers (one Democrat, one Republican) on charges related to corruption.
