A unanimous vote by the U.S. House last night has brought new attention to Rep. Bill Posey’s attempt to require presidential candidates to submit their birth certificates to prove they are really U.S. citizens. But Posey is not backing down.

As part of a lingering and, many feel, stupefying controversy over whether President Barack Obama was born in the United States, the House passed a resolution 378-0 celebrating the 50th anniversary of Hawaiian statehood and also recognizing it as Obama’s birthplace. Posey, R-Rockledge, joined the majority as did co-sponsors of his bill.
