Seven secret plans – some highly compartmented – exist to prepare for these extraordinary missions. Three are transportation related, just to move and support the White House and the federal government as it evacuates and operates from alternate sites. The first is called the Rescue & Evacuation of the Occupants of the Executive Mansion (or RESEM) plan, responsible for protecting President Trump, Vice President Mike Pence, and their families–whether that means moving them at the direction of the Secret Service or, in a catastrophe, digging them out of the rubble of the White House.

The second is called the Joint Emergency Evacuation Plan (or JEEP), and it organizes transportation for the Secretary of Defense and other national security leaders so that they can leave the Washington area. The Atlas Plan is a third, moving non-military leaders – Congressional leadership, the Supreme Court and other important figures – to their emergency relocation sites. Under Atlas, a still- secret bunker would be activated and cordoned, with government operations shifting to Maryland.

The three most compartmented contingencies – Octagon, Freejack, and Zodiac – call upon various military units in Washington DC, North Carolina and eastern Maryland to defend government operations if there is a total breakdown. The seventh plan – codenamed Granite Shadow – lays out the playbook for extraordinary domestic missions that involve weapons of mass destruction. (I disclosed the existence of this plan in 2005, and its associated “national mission force”–a force that is on alert at all times, even in peacetime, to respond to a terrorist attack or threat with the nuclear weapon.)
