The stunning protest of four career prosecutors who withdrew from the Roger Stone case or resigned from government service will long be remembered as one of the most dramatic moments at the U.S. Justice Department in the tumultuous Trump era.

The prosecutors—Jonathan Kravis, Michael Marando, Adam Jed and Aaron Zelinsky—refused to sign onto maneuvering by U.S. Attorney General William Barr’s Justice Department to retract a sentencing memo that said Stone, a longtime ally of President Donald Trump, should face between seven and nine years for lying to Congress and other crimes.
