WATCH LIVE: Sarah Sanders holds White House press briefing after Manafort and Cohen bombshells

Former Donald Trump White House adviser Alyssa Farah Griffin tore into her former boss on Thursday for his conduct in the Mar-a-Lago classified document theft investigation.

Trump has long claimed he has blanket declassification authority, but new reports show he was caught on audio discussing a highly classified document laying out an attack plan against Iran, and admitting he doesn't have full authority to declassify military secrets — something that should come as no surprise, Griffin argued, because she saw firsthand that Trump understood this.

Former President Donald Trump's defense that he was allowed to mentally declassify the top-secret documents stashed at Mar-a-Lago has been thrown into chaos by reporting showing that audio tapes exist of Trump telling people he possessed a document showing plans to attack Iran, but didn't have the authority to show it to them.

But more interesting, argued New York University law professor Ryan Goodman, is the reports that Trump apparently wanted to use the document to embarrass Gen. Mark Milley and pin efforts to invade Iran on him.
