Am I the only one hoping for Arnold Schwarzenegger as secretary of energy?
I'm fairly certain that's illegal, as he was born in Austria.
Since he is friends with the Terminator, he might choose (one of) Schwarzenegger's brother-in-law, the former Mayor of Santa Monica, Bobby Shriver, or the former Maryland State Delegate, Mark Shriver, or the Chairman of the Special Olympics, Timothy Shriver, or the former potential Democratic candidate for Governor of Florida in 2006 and 2010, Anthony Shriver.
It isn't illegal. The current Secretary of the Interior, Sally Jewell, was born in the UK and is not a natural born citizen. She just isn't in the line of succession.
