Fourteen former national security, intelligence, and foreign policy officials who have served at senior levels in Republican and Democratic administrations recently wrote an amicus brief as part of a lawsuit brought against President Donald Trump's campaign and Roger Stone, his longtime confidant.

Among the former officials who filed the amicus brief on December 8 are John Brennan, a CIA director; James Clapper, a director of national intelligence; and Michael Hayden, a director of the National Security Agency; Avril Haines, a deputy national security adviser; Michael McFaul, a US ambassador to Russia; and Michael Morell, an acting CIA director.
