From Vixen Strangely at Strangely Blogged:
Donald Trump is an uniquely disingenuous man. He is a liar. It’s what’s for breakfast, lunch, and dinner with Trump–he is going to lie about something. He decided to lie and say he thought maybe Barack Obama was not eligible to be president because of his birth certificate. I would like everyone, everyone please! Stop pretending Donald Trump started birtherism. It was just a thing that was around message boards and blogs in 2008 and to their ever-lasting shame, some PUMA-types need to own up that they kind of liked the idea that this was a fun way to kneecap a credible African-American candidate. But no. There were so many fathers and mothers of this failure–Orly Taitz. Jerome Corsi. Near as I can tell, this was never a spectacular issue for Trump until about 2011 or so.
It doesn’t appear to be at all true that he stopped after the birth certificate was put out by President Obama.
