President Obama arrived on the Vineyard yesterday afternoon to begin a 10-day vacation with his family, marking his third consecutive August visit to the Island during his presidency. Like the last two years, the arrival was low-key and closed to the public. Traveling with the President were White House counterterrorism chief John Brennan and deputy press secretary John Earnest, White House trip director Marvin Nicholson, White House photographer Pete Souza, and the family dog, Bo, freshly groomed for the trip.
