Attorney General Jeff Sessions asked all of the U.S. attorneys appointed by President Barack Obama who are still in their posts to submit their resignation on Friday, paving the way for the Trump administration to remake federal prosecutors’ offices around the country.

Notably, the request appeared to backtrack on an earlier request by President Donald Trump for Manhattan U.S. Attorney Preet Bharara, well-known for his aggressive prosecutions of insider trading and corruption in New York, to remain in that job.
