Former CIA Director John Brennan, a vocal critic of President Trump, found out he had been blocked from accessing his classified notes and records while working on his new memoir.

He writes in his forthcoming book, Undaunted: My Fight Against America’s Enemies, at Home and Abroad, that after months of “haggling” he discovered the CIA was abiding by the directive Trump gave in August 2018 “that purportedly forbids anyone in the intelligence community from sharing classified information with me.”
