Geoffrey Berman, who oversaw the criminal prosecutions of President Donald Trump's associates and foes, has resigned as U.S. attorney for the Southern District of New York, according to a statement from the Justice Department.

After the sudden announcement by U.S. Attorney William Barr, President Donald Trump named Jay Clayton, chairman of the Securities and Exchange Commission, as his choice to take over the Manhattan federal prosecutor's office.

But Berman said in a statement contradicted the resignation narrative.
