Yankee White - S1-E1
Character mistake: The uniform/costume that Major Tim Kerry, a Marine Military Aide to the President, is wearing, includes a Service Aiguillette made of 4 loops of round gold wire and scarlet cord. This aiguillette is worn by a Marine serving as an Aide or in other positions for a 4 Star General. A military aide to the President would wear 4 loops, all gold (as seen being worn by Commander Ray Trapp). (00:29:00)
