While it certainly reads like a bad Vince Flynn novel plot, I admit to being a bit intrigued by the notion that there might be a secret Executive Order that attempts to override the well-known order of succession to the Presidency in the case where both the President and Vice President die or are incapacitated. Exhibit A of the argument is the fact that there’s both a secret appendix and another set of classified appendices to the 2007 Presidential Succession Act (“Annex A” and the “classified Continuity Annexes”); exhibit B is that apparently, Reagan was the one to issue the original order, and nobody knows what happened to it in the intervening years. Interesting.
