New York Times: “The call to Preet Bharara’s office from President Trump’s assistant came on Thursday. Would Mr. Bharara, the United States attorney in Manhattan, please call back?”
“It was unclear whether the president’s call on Thursday was an effort to explain his change of heart about keeping Mr. Bharara or to discuss another matter. The White House would not comment on Saturday.
However, there are protocols governing a president’s direct contact with federal prosecutors. According to two people with knowledge of the events who were not authorized to discuss delicate conversations publicly, Mr. Bharara notified an adviser to the attorney general, Jeff Sessions, that the president had tried to contact him and that he would not respond because of those protocols.”
