“recess appointment”
Yep. Trump can also name any cabinet level official as acting AG until the senate confirms.
Wouldn’t be acting. If Sessions leaves for DHS, he can bring in EPA Chief Scott Pruitt as new, PERMANENT Attorney General WITHOUT having to go thru confirmation. Same with Sessions going to DHS - he won’t need to go thru confirmation a second time. He’s already been vetted and confirmed to serve in the cabinet till Noon EST, January 20, 2021. He can be moved to any other cabinet position of the President’s choosing without having to be reconfirmed.
