Working in lockstep with the Republican-controlled Senate, Trump may have the longest-lasting impact on the federal courts with judicial appointees who tilt to the right. In less than four years, Trump has appointed three justices to the Supreme Court, a feat last achieved by President Richard Nixon, who appointed four in his first four years. The nation’s highest court now has a solid 6-3 conservative majority. Trump has appointed 53 judges to federal appeals courts, just under a third of the total. By comparison, former President Barack Obama appointed 55 in his two four-year terms. Trump has appointed about a quarter of district court judges, the lowest rung on the federal judicial ladder.
