The AP asked Rosenstein specifically whether Mueller’s investigation could expand to include examining Sessions’ role.
“The order is pretty clear,” Rosenstein responded. “It gives him authority for the investigation and anything arising out of that investigation, and so Director Mueller will be responsible in the first instance for determining what he believes falls into that mandate.”
Rosenstein told the AP that if he were to become a subject of Mueller’s investigation, he would recuse himself from any oversight of Mueller. Under Justice Department rules, Mueller is required to seek permission from Rosenstein to investigate additional matters other than ones already specified in the paperwork formally appointing Mueller.
