You should have asked why America has to answer to his father, who had a child by a woman not his wife. Let him say that it was nothing but a "personal mistake, can't we all just move on?" about that!
Uh...I thought he DID say something to that effect when the fertilizer hit the fan. IIRC, he also explained his bringing his MISTRESS to the WH while 'personally ministering' to Bubba as a 'personal mistake', too.
