When Donald Trump moved on his first day back in office to strip birthright citizenship from children born in the U.S. to some immigrant parents, U.S. District Judge John Coughenour called the newly inaugurated president a threat to the rule of law.

Days after Trump mass-pardoned Jan. 6 defendants who attacked the Capitol, U.S. District Judge Royce Lamberth warned that for the first time in his career, “meritless justifications of criminal activity have gone mainstream.”

And in September, U.S. District Judge William Young warned that Trump’s crackdown on pro-Palestinian immigrants studying at U.S. universities “poses a great threat to Americans’ freedom of speech.”

In a year full of judicial rebukes for the president — often followed by vindication for Trump at the Supreme Court — these judges’ fierce and direct assessments of the president have stood out. But there’s more than lofty rhetoric that binds them. All were appointed to the bench decades ago by the same president: Ronald Reagan.

Now a fourth member of the Reagan-era fraternity has joined them: U.S. District Judge Mark Wolf, who took the bench in Massachusetts 40 years ago on the same day as Young. Wolf resigned his senior judgeship last week with the sole purpose of speaking out against what he sees as Trump’s incursion on the rule of law and the high court’s acquiescence to it.
