Preet Bharara, the US attorney for the Southern District of New York and an Obama-era Justice Department appointee, was fired by President Donald Trump on Saturday after refusing to submit his resignation to Attorney General Jeff Sessions.
Bharara earned a reputation as the "Sheriff of Wall Street" for his high-profile prosecutions of white-collar criminals from 2009-2017. Bharara has won cases against CEOs, arms dealers, banks, and hackers.
Here's a rundown of some of Bharara's most noteworthy cases during his time as US attorney.

In November 2016, Bharara's office arrested a former Valeant executive and former Philidor CEO on charges of engaging in a multi-million dollar fraud and kickback scheme.

In 2015, Bharara's office charged three men accused of helping to run a sprawling series of hacking and fraud schemes, including a huge 2014 attack against JPMorgan Chase & Co, that generated hundreds of millions of dollars of illegal profit, according to Reuters.

After Bharara brought felony charges against JPMorgan Chase in 2014, the bank paid $1.7 billion to settle charges that it failed to act against Bernie Madoff's suspicious activities at the height of his Ponzi scheme. The settlement was the largest forfeiture demanded from a bank in US history, according to Reuters.
