A Washington lobbying firm with veterans of the Clinton and Obama administrations is joining a growing Democratic effort that puts the federal judiciary—both shaping the courts and resisting Trump administration nominees—in sharper focus within the political arena.

The Raben Group registered Thursday to lobby on judicial nominations for a closely affiliated nonprofit, the Committee for a Fair Judiciary (CFJ), which was founded in 2011 to address the perceived enthusiasm gap on the left that relegates the importance of judicial nominations. Republicans, on the other hand, have long rallied around the courts, and the Trump administration is reshaping the judiciary with a crop of young, largely white and male, court nominees.
