By saying “this is his out” ...I am referencing his claim that he was too afraid to find out..not the whole mysterious BC issue.
In other words, he spent all his life claiming his mother was married to his father. If it comes out that wasn’t true..he just says..I was too afraid to find out....not, yeah I knew about it and lied through my teeth.
(A politician who is a bastard and lies? The horror!)
