Rep. Adam Schiff, the top Democrat on the House Intelligence Committee, said on Tuesday that two top officials from the Justice Department and FBI told him that President Trump’s order to declassify Russia-related documents was a “red line” that must not be crossed.

During an interview on CNN, Schiff, D-Calif., expounded upon a statement he released Monday, saying it was FBI Director Christopher Wray and Deputy Attorney General Rod Rosenstein who issued a warning about national security.
