From Fact Check dot org:
The latest development in the saga of the so-called “birther” challenges to Barack Obama’s presidency comes from Hawaii, Obama’s native state. Yesterday, Gov. Linda Lingle (a Republican–ed.) signed a law allowing state agencies to ignore requests for information if they determine the requests duplicate or are substantially similar to earlier ones. The law targets those who contend Obama wasn’t born in the U.S. and thus, under the Constitution, can’t be president; they still are sending 10 to 20 e-mails every week asking the state’s Health Department for verification of his birth certificate. Some file the same request even after receiving a response.
(As journalists, we wonder, “Since when has a government official needed a law to ignore a request for information?” But we assume Hawaii officials have their reasons.)
Shorter version: Hawaii is tired of wasting its time with whackjob looney bigots.
