President Barack Obama had a bit of fun this past weekend at the annual White House Correspondents’ Dinner, where he opted to walk out to DJ Khaled‘s “All I Do Is Win” instead of the time-honored presidential anthem, “Hail To The Chief.” The POTUS’ decision to change the entrance music was the first nod to rap in an evening that would be peppered with hip-hop artists and references. President Obama let his hair down and went on to reference Jay-Z‘s “99 Problems” during a joke about the controversy over the rapper’s recent trip to Cuba with wife, Beyoncé. The President’s comedy routine was countered by a more somber moment of reflection as he thanked the first responders who raced to aid victims of the Boston Marathon bombing. He urged members of the press and those elsewhere in positions of power to work more selflessly on behalf of the people of the United States of America. The evening was capped by an after-party featuring performances from The Roots and Biz Markie. Check the video from CSPAN below to see the POTUS’ full address.
