Trump is on a mission to replace overly liberal Federal judges. That have been making irrational decisions, and who have been trying to push liberal views from the bench. I can't help but wonder if this decision was a result of their fear of his actions.
Trump does what he say's. And he is not afraid of any political repercussions from the liberal media. Trump is famous for a, "tow the line or you're out", attitude. Judges have cushy jobs, and they don't want to lose them. Regardless of their political viewpoint.
