But that stance clashed with the disclosure by two officials that the intelligence was included months ago in Mr. Trump’s President’s Daily Brief document — a compilation of the government’s latest secrets and best insights about foreign policy and national security that is prepared for him to read.

Even in those face-to-face meetings, he is particularly difficult to brief on national security matters. He often relies instead on conservative media and friends for information, current and former intelligence officials have said.
