You didn’t hear about what Obama did? He declared the senate to be in recess, when it wasn’t. Because only the senate can declare itself in recess. Obama declared it was, anyway, and appointed people he wanted. A lower federal court than SCOTUS already weighed in and said it was unconstitutional/illegal, but Obama blew off the ruling and those people still sit in their appointive jobs today.
And ever one of their decisions/opinions can be or will be challenged.
The Senate will be in recess for the next 20 years.
The whole Obama planned Pesidency.
