HONOLULU  Gov. Neil Abercrombie of Hawaii, who befriended President Obama’s parents when they were university students here, has been in office for less than three weeks. But he is so incensed over “birthers”  the conspiracy theorists who assert that Mr. Obama was born in Kenya and was thus not eligible to become president  that he is seeking ways to change state policy to allow him to release additional proof that the president was born in Honolulu in 1961.

“It’s an insult to his mother and to his father, and I knew his mother and father; they were my friends, and I have an emotional interest in that,” Governor Abercrombie said in a telephone interview late Thursday. “It’s an emotional insult. It is disrespectful to the president; it is disrespectful to the office.”

The governor, a Democrat and former congressman, said he has initiated conversations with the state’s attorney general and the chief of its Health Department about how he can release more explicit documentation of Mr. Obama’s birth on Aug. 4, 1961, at Kapiolani Maternity and Gynecological Hospital. He said he has done so of his own accord, without consulting the White House, which declined to comment.
