General Thomas was United States Army officer in service in Washington, D.C., during Day 4. At 12:30am, General Thomas reported to President Charles Logan in the Presidential bunker that a nuclear warhead had been stolen from a convoy moving through Illinois by terrorists working for Habib Marwan. President Logan was extremely disconcerted and spoke with Mike Novick immediately after. ("Day 4: 12:00am-1:00am") Some time later, Thomas was present while Logan, Novick, and Walt Cummings debated whether to authorize the interrogation of Joe Prado, one of Marwan's associates.
