The problem is, unless I am mistaken, that McConnell hasn't technically allowed the Senate to fucking HAVE a single recess since POTUS was sworn in. He's pulling this procedural stunt deliberately, of course, specifically to prevent POTUS from making recess appointments. I vaguely remember POTUS complaining about this in public at some point, maybe it was at one of his rallies?
It means that even when the senatorial swamp creatures are all on their summer or Christmas vacations, they're still technically "in session" so there's no "recess." That fucker McConnell…
