Two district judges rescinded their announced plans to take senior status following the election of Donald Trump. Mitch McConnell is not pleased.
Whether McConnell (who held open a SCOTUS seat for more than a year to manipulate who would fill it) has standing to complain about gamesmanship is up for debate. But recall the criticism of life tenure (and a reason to even appointments) as to SCOTUS has been justices manipulating retirements. This shows (and there are other examples) how the problem is not limited to SCOTUS but has trickled to lower courts.
