they could take steps to prevent that. they could hold what s called a proforma session which means the senate is de facto in session, it s not technically in recess so the president cannot make a recess appointment. that s something that a senator in nebraska floated on the senate floor this week. there s maneuvering behind the scenes there to try to prevent the president from taking such a step. is that going to be led then by mitch mcconnell, or senator sass is one but is mcconnell going to go along with that? it depends, that s a big question for the senate majority leader but remember everything in the senate is done by unanimous consent so one senator can essentially effect the process there, so there s a lot of rumbling behind the scenes, they might prevent that from happening. and don t forget that the chairman chuck grassley has said that if president trump decides to get rid of jeff sessions that he s not going to hold any hearings on any new nominee this year.
