Family Separation: Part 2 - S5-E11
Trivia: What political party viewpoint does President Dalton associate with on the show? Even though there is political discourse on the show, Madam Secretary has done an amazing job of not naming political parties. However, a revealing political fact occurred when President Dalton is in a heated video teleconference with the Governor of Arizona and behind the governor is a framed picture of President Reagan. Therefore, the show finally makes a reference to a political party - the governor identifies with the Republican Party and President Dalton is not a Republican. (00:17:00)
Trivia: In the flashback scene at the beginning of Episode 4, the young Stavros Milos finds a case of money buried in the snow, next to a fence on the road where his car runs out of gas.
