A synopsis from vettingroom.org called the nomination of Trump’s Ninth Circuit Court Nominee Ryan Nelson is a move to shift the court to the right.
The Ninth Circuit has a (somewhat undeserved) reputation as an overly liberal court, and has attracted the President’s scorn for some of its rulings.  As such, the nomination of the conservative Nelson could be touted (in some circles) as an effort to shift the court to the right.  But setting the ideology of the pick aside, Nelson’s background in environmental law is particularly suited to the Circuit covering some of the country’s most scenic public lands.
