Secret Service agents never expressed concern that Friday night's blackout might have been a threat toward President-elect Barack Obama, who is vacationing at a beachside compound in Kailua, Gov. Linda Lingle said yesterday.

"There was never any talk like that in the Civil Defense headquarters" inside Diamond Head crater, Lingle said. " ... There were no communications of that nature. From the very beginning, it was thought to be something weather related."

Initially, however, Lingle was concerned that Obama's presence on O'ahu would result in "national and international news coverage that Hawai'i might get of a negative nature," which did not materialize.

Obama's transition team yesterday issued a statement that said power went out at the Obama compound around 7 p.m. Friday and returned around 6 a.m. yesterday.

Mayor Mufi Hannemann had offered Obama and his family assistance and supplies, including a generator, which were declined. The mayor said he continued checking on Obama and his family throughout Friday evening.

Hawaiian Electric Co. did deliver a generator to the Obamas, Hannemann said.

"The Obama family is grateful for the offers of assistance from local officials," said Ben LaBolt, Obama's spokesman.

While power was slowly coming back to parts of O'ahu yesterday, Obama resumed his morning workout routine at the Semper Fit Center at Marine Corps Base Hawaii, near his vacation home.

He was joined by his wife, Michelle, and Chicago friends Valerie Jarrett, Eric Whitaker and Martin Nesbitt.

Michelle Obama and Jarrett left the Semper Fit Center at 8:48 a.m., an hour after they entered. President-elect Obama, Whitaker and Nesbitt left about 16 minutes later.

Obama emerged flashing a shaka.

He moved through a line of people, greeting them. He hoisted four babies and posed for pictures with them.
