Is 0 does a recess appointment how long does it last and is there anything the Senate can do about it and when
The next session will start on January 3rd, 2017.
Given that, I don't think they're in recess in at all when one Congress ends and then another begins.
Mitch McConnell was officially elected Senate Majority Leader on January 3rd, 2015. So the NEW Senate started business on that day.
