President Obama paid a surprise Christmas Day visit to Marines celebrating the holiday in Hawaii. Obama will be on the island until Jan. 2. Obama, along with family and friends, took in some NBA basketball. The president has spent the last few days playing golf, exercising, and reading. He is said to have brought a biography of Ronald Reagan along with him. Last Christmas was less relaxing thanks to the failed attempts of the "Underwear Bomber" on a plane over Detroit.
