After years of insisting otherwise, the GOP nominee acknowledged on Friday that the president was, in fact, born in the United States. Clinton said, however, that his admission was a "disgrace" as he expressed "zero regret."
@HillaryClinton: Expressing zero regret for years of pushing a racist conspiracy theory, Trump again appointed himself judge & jury on @POTUS's citizenship.
