Donald Trump just fired Preet Bharara — here’s a look at the Sheriff of Wall Street’s most high-profile cases

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.

In March 2014, Bharara's office charged Toyota with one count of wire fraud for lying to customers about safety issues with Toyota-manufactured cars. Toyota eventually paid out a $1.2 billion fine, which was the largest criminal penalty ever doled out to an automaker.

In one of his most high-profile cases as a federal prosecutor, Bharara in 2013 unveiled criminal fraud charges against billionaire Steven A. Cohen's SAC Capital Advisors LP, capping a nearly seven-year probe into one of Wall Street's most renowned firms. The parties eventually reached a $1.8 billion settlement, the largest ever for insider trading, and the firm agreed to shut its doors.

In 2012, Bharara brought charges against Mathew Martoma. Martoma, who worked for CR Intrinsic Investors in Stamford, a unit of SAC Capital, was accused of making more than $276 million in illicit profits based on tips about Elan Corp and Wyeth LLC, which was bought by Pfizer in late 2009.

Bharara was featured in TIME Magazine's 2012 list of the world's 100 most influential people. He was also featured on a cover of the magazine titled, "This Man Is Busting Wall Street" because of his office's work in prosecuting insider trading and financial crime.

Under Bharara's leadership in 2010, the SDNY federal prosecutor's office brought terrorism charges against suspected Russian arms dealer Viktor Bout. Bout, a former Soviet air force officer dubbed the "Merchant of Death," was accused of trafficking arms to dictators and conflict zones in Africa, South America and the Middle East throughout the 1990's and early 2000's, according to Reuters. He was convicted in November 2011.
