Anderson Cooper 360º: Special counsel will oversee Trump federal criminal investigations

Attorney General Merrick Garland appointed a special counsel to oversee the federal criminal investigations into former President Trump. Jack Smith will look into the retention of national defense information at Trump’s Mar-a-Lago resort and parts of the January 6 insurrection. Former FBI Deputy Director Andrew McCabe tells AC360 what this announcement says about where investigators are in their probes.

Plus, authorities are still looking for a suspect five days after four University of Idaho students were fatally stabbed in their off-campus home. Garrett Cabeza is a reporter for the Spokesman-Review. He joins AC360 to give an update on the investigation.
