Day 5: 11:00 A.M.-12:00 P.M. - S5-E5
Factual error: When Mrs. Logan escapes, Aaron Pierce refers to her as "the First Lady" over his radio. The Secret Service has code names for each of the members of the president's family. He should have used her code name when communicating to other Secret Service agents about her.
Day 5: 1:00 AM - 2:00 AM - S5-E19
Factual error: When Chloe is at Bill's, she brings up the details of the diplomatic flight, and it shows the aircraft as a Boeing 757-200. This is a twin-engine aircraft, but the one shown is a tri-jet.
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
