After Trump was elected Mitch McConnell went to the Press and stated he would never allow the Senate to officially recess and allow President Trump the ability to make any recess appointments.
As of now McConnell has used parliamentary tricks to keep the Senate in session for just that reason.
I used to call McConnell, yertle the turtle, but that was wrong. He’s a snake. ( I have to give him credit for not relenting on Kavanaugh, though. Someone must have milked his fangs that day.
