Preet Bharara, the United States attorney for the Southern District of New York, is among the prosecutors whose resignation President Trump has ordered.

WASHINGTON (Diya TV) — Former U.S. attorney Preet Bharara, who was removed from his post by the Trump administration last week, was reportedly overseeing an investigation into stock trades made by President Trump’s Health and Human Services secretary Tom Price.

Price previously came under scrutiny during his confirmation hearings for investments made during his tenure in Congress. The Georgia lawmaker traded hundreds of thousands of dollars worth of shares in health-related companies, even as he voted on and sponsored legislation affecting the industry.

Price testified that his trades were lawful and transparent, but that didn’t stop Democrats from accusing him of potentially using his office to enrich himself financially. One lawmaker called for an official investigation to be conducted by the Securities and Exchange Commission, citing concerns Price could have violated the STOCK Act, a 2012 law signed by President Obama that clarified that members of Congress cannot use nonpublic information for profit and requires them to promptly disclose their trades.

The investigation of Price’s trades by the U.S. Attorney’s Office for the Southern District of New York, which hasn’t been previously disclosed, were reportedly underway at the time of Bharara’s dismissal.

Bharara was one of 46 acting U.S. attorneys asked to resign after President Trump took office. It’s a running tradition for an incoming president to replace those officials with their own appointees, however, Bharara was one of the attorneys summoned to Trump Tower during the transition, where the President-elect asked the 48-year-old to stay on with the new administration. At the time, Bharara told reporters in the lobby of Trump Tower that he had agreed to stay on.

When the Trump administration instead asked for Bharara’s resignation, the prosecutor refused, and he said he was then fired. Trump has not explained the reversal, but Bharara fanned suspicions that his dismissal was politically motivated via his personal Twitter account.

“I did not resign,” he wrote in one tweet over the weekend. “Moments ago I was fired.”

“By the way,” Bharara said in a second tweet, “now I know what the Moreland Commission must have felt like.”

He was referring to a commission launched by New York Gov. Andrew Cuomo in 2013 to investigate possible state and government corruption, only to be disbanded by the governor the next year as the investigation moved closer and closer to his own office. In that case, Bharara vowed to continue the commission’s work, and eventually charged Cuomo associates and won convictions of several prominent lawmakers.

In December, the Wall Street Journal reported that Price traded more than $300,000 worth of shares in health companies over a recent four-year period. Price, an orthopedic surgeon by trade, chaired the powerful House Budget Committee and sat on the Ways and Means Committee’s health panel.
