Mac takes Amy's breakfast muffin

The song played by the band in the closing minutes of the show was "Mack the Knife" composed by Kurt Weill and lyrics written by Bertolt Brecht.
What Mac does not mention about President John Tyler is that he only got to serve out the term that his predecessor William Henry Harrison was elected for and left office without being elected in his own right. In fact it was not until Theodore Roosevelt who became the first Vice-President to accede to the Presidency due to the death of his predecessor to be elected in his own right. Perhaps that's why President Bridges was named after Roosevelt.
Despite what is being stated on-screen, the National Security Advisor is not a member of Cabinet.
