Factual error: FBI Agent Hannah Wells pulls up to the house of the First Lady's mother driving a unmarked police vehicle with government license plates. The license plate is I410918, which is a Department of Interior plated vehicle. The FBI wouldn't be driving a Department of Interior vehicle as the FBI is in the Department of Justice. A Justice plate would have a J and a FBI agent vehicle would have a regular license plate. (00:14:00)
Factual error: The dirty bomb went off at the Brandt Metro station. There is no station with that name.
Answer: The line of succession is VP, Speaker, President Pro Tempore, then the Cabinet Secretaries in the order the department was created.
