The nation’s top spy office announced that it will switch its future election security briefings to Congress from being in-person to being conducted in writing, saying the change was due to concerns about classified leaks and politicization of intelligence.

“In order to ensure clarity and consistency across the Office of the Director of National Intelligence’s engagements with Congress on elections, the ODNI will primarily meet its obligation to keep Congress fully and currently informed leading into the Presidential election through written finished intelligence products,” Director of National Intelligence John Ratcliffe informed congressional leaders in letters obtained by the Washington Examiner.
