“We differ from one another in our politics, and we also differ from one another on issues of constitutional interpretation,” wrote the signatories, which include the co-founder and other members of the conservative Federalist Society legal group. “But despite our differences, our carefully considered views of the law lead all of us to agree that the Constitution permits the impeachment, conviction, and disqualification of former officers, including presidents.”

More than 150 legal scholars signed on to the letter, which was obtained by POLITICO. They include Steven Calabresi, the co-founder of the Federalist Society; Charles Fried, who served as solicitor general under Ronald Reagan and is now an adviser to the Harvard chapter of the Federalist Society; Ilya Somin, a law professor at George Mason University and adjunct scholar at the libertarian Cato Institute; and Brian Kalt, a law professor at Michigan State University and leading scholar on the specific question of whether former officials can be impeached.
