Are Trump Judges Different? Evidence from Immigration Cases

By Daniel M. Klerman

Judges appointed by President Trump are more likely to vote in favor of the government in cases challenging the second Trump administration's immigration policies. While Trump's Supreme Court nominees behave like other Republican nominees on the Court, Trump's lower court nominees are twice as likely to vote in favor of the government as nominees of other Republican presidents; in contrast, other Republican nominees to the lower courts are statistically indistinguishable from Democratic nominees. The difference between Trump nominees and other judges is driven almost entirely by judges 55 years old or younger, who may be influenced by the prospect of promotion to the Supreme Court.
