The power of the president is enormous. As Mr. Trump stated in March, "I have the right to do a lot of things that people don't even know about." What the president appears to have been referring to are his presidential emergency action documents, often referred to as PEADs. "Even though I've had security clearances for the better part of 50 years and been in and out of national security matters during that half-century, I had never heard of these 'secret powers,'" said former Senator Gary Hart. Ted Koppel asked, "Do you know what they are, now that you've heard of them?" "Only vaguely, due to research done at the Brennan Center for Justice," Hart said. "What these secret powers are, apparently, based on the research, is suspension of the Constitution, basically." The Brennan Center research that Senator Hart referred to has been spearheaded by Elizabeth Goitein. Goitein says what little we do know about PEADs comes from references to them in other documents, some of which are now declassified. "They originated in the Eisenhower administration," Goitein said. "But since then ... no presidential emergency action document has even been released, or even leaked. Not even Congress has access to them. Congress is not aware of these documents, and from public sources we know that at least in the past these documents have purported to do things that are not permitted by the Constitution - things like martial law and the suspension of habeas corpus and the roundup and detention of people not suspected of any crime."
