President Donald Trump’s steady march to reshape the U.S. Court of Appeals for the Ninth Circuit hit a snag Thursday.

Just as Trump’s first Ninth Circuit nominee, Oregon federal prosecutor Ryan Bounds, was set to come up for a full Senate vote, Majority Leader Mitch McConnell announced the nomination had been withdrawn. The announcement came after his home-state Democratic senators opposed Bounds nomination, and as reports surfaced that Sen. Tim Scott, R-South Carolina, had concerns about the nominee’s college writings in which Bounds criticized “race-based” campus groups and efforts to promote multiculturalism.
