President Trump’s two Supreme Court appointees went to the same Jesuit high school in the Washington suburbs — at the same time. After attending Ivy League colleges and law schools, they worked as law clerks on the Supreme Court — for the same justice, in the same term.

They served as appeals court judges for more than a decade, turning out opinions that captured the attention of conservative legal groups like the Federalist Society and the Heritage Foundation. They were confirmed by tight votes, mostly along party lines.

On the Supreme Court, they were widely expected to be jurisprudential twins. But it turns out that there is more than a little daylight between Justice Neil M. Gorsuch, who joined the court in 2017, and Justice Brett M. Kavanaugh, who started in October after facing accusations of sexual assault, which he denied, at his confirmation hearings.
