President Trump says he hopes Justices Clarence Thomas and Samuel Alito stay on the Supreme Court “a long time,” but behind the scenes, court watchers are closely eyeing their age, timing, and what a retirement could mean for the court’s future. With elections looming and a friendly Senate (for now), the question isn’t just if a vacancy will open — but when, and under whose control.
Any vacancy would give Trump the opportunity to make a fourth appointment to the court. The last president to appoint four justices was Republican Richard Nixon, who served from 1969 to 1974.
