Sounds like Twitter fodder for the White House enemies: President Obama is keeping plans for a 10-day vacation in Martha's Vineyard later this month, reports USA Today. "I don't think Americans out there would begrudge that notion that the president would spend some time with his family," said spokesman Jay Carney. Besides, he added, presidents aren't ever really on vacation. "The presidency travels with you." The Obamas head to Massachusetts on Aug. 18.
