The president says "the right to privacy is a value," a callback to The Short List (1999) when Sam was talking about the potential of possible Supreme Court nominee Peyton Cabot Harrison III and said the right to privacy was going to be a big issue in the future.
Air Force One is unlikely to land at a commercial airport (SNA is the airport code for John Wayne Airport) if a military option is available (as is Los Alamitos).
Early in the episode, CJ makes reference to "Operation Safe Haven" during the press briefing. In real life there have been at least a two military operations and two investigations with this name including the humanitarian mission to airlift Hungarian refugees from Europe to the US in 1957 and the 1994/1995 humanitarian mission to provide and care for 10,000 Cuban migrants attempting to cross the Florida Straights in summer 1994.
This district is now the California 48th district and was represented by Congressman Dana Rohrbacher (R) from 2003-2018. It is currently represented by Congressman Harley Rouda (D).
CJ (Allison Janney) 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.
