The West Wing Season 4 Episode 16

CJ makes a big deal about some miscommunication between AF1 and the CHP, stating Interstate 5 has been closed (presumably for the motorcade) and the CHP thought they would land in Santa Ana when they are supposed to land in Los Alamitos. Despite this comment from CJ, later in the episode Sam mentions airport traffic at John Wayne being on hold, implying AF1 landed there. Also, getting to Newport Beach from Santa Ana or Los Alamitos would not require the 5 Freeway, but the 405 Freeway. There is also mention of people being stuck in Disneyland waiting for the motorcade. We don't know where these people have to go to get home, but the route from either airport to Newport doesn't go anywhere near Disneyland.
