PolitiFact's guide to Obama's birth certificate

Originally published April 8, 2011

Nothing we've published in the four-year history of PolitiFact has generated as much interest as our coverage of President Barack Obama's birth certificate.

New allegations from Donald Trump (new from Trump, at least; most of them have been explored by PolitiFact and other fact-checkers) have prompted fresh interest in the subject, so we thought we'd provide a handy guide to our coverage.

The main stories

Obama's birth certificate: the final chapter -- This time we mean it! explored additional angles of the story and included an explanation from Hawaiian officials and confirmation that the birth certificate posted by the Obama campaign was legitimate.
