A one time U.S. Attorney Preet Bharara said Sunday that President Trump called him three times but he didn’t pick up one of those calls.

Bharara was fired in March by President Donald Trump when he refused to resign along with other attorneys who served in the Justice Department during the Obama administration. The rift came as a result of several conversations he had with Trump during the period of his transition to the presidency. Bharara said he had unusual calls with him on at least two occasions.

Trump's controversial calls

Bharara told reporters that when he read the news of how President Trump had contacted James Comey former FBI director multiple times, he felt a little bit worried.

Bharara was invited to Trump Tower by the President weeks after the election; he further said that Trump asked him to stay over at the time. He added that Trump called him twice during the period of transition.

The former attorney said he was a little bit uncomfortable. According to Bharara, Trump was not president yet. He was just a President-elect. He explained that the President called once more in March after he was sworn-in as President but Preet declined to return the call.

Bharara said he discussed with his team and reported the series of phone calls by the president, to the chief of staff to Attorney General Jeff Sessions, explaining that it seemed Trump was making attempt to develop some kind of relationship with him.

Avoiding Trump

He said it was necessary for him to stay at a distance from Trump owing to the jurisdiction of a U.S. attorney over business interests which includes the New York’s Trump Organization.

He also said President Trump knew such an approach was implicative. Bharara stated that he and other U.S. attorneys were asked to resign 22 hours after he refused to return the President’s call.

Ample evidence to institute a probe

In an interview held on Sunday by ABC News, Bharara said he believes there is ample evidence to warrant a probe against the president for his deliberate act of obstructing justice, but he advised people not rush to a conclusion on either side.

The former U.S. attorney said he felt Robert Mueller, Justice Department special counsel would consider obstruction of justice as a sub of the executive branch’s probe, adding it would be a logical move, “If Robert Mueller is considering everything that you may wish him to look at. Successful prosecutors consider everything, and this seems to be among one of those things he would be considering.”
