What’s False
… but, officially, he has only changed his name twice, not three times. The first name change was the result of his adoption by his stepfather. The second name change was one he requested as he was about to graduate from Yale Law School, a year before he got married.
His choosing of his own name while wanting to deny the same right to others is hypocritical and part of his being an asshole.
