Prince William In Washington, Meets With President Obama.

Prince Williams flew to Washington this morning to meet with the President and deliver a speech at the World Bank on stopping illegal wildlife trafficking. Prince William left his pregnant wife Kate, the Duchess of Cambridge, in New York City - where the couple arrived Sunday night to a rock star welcome.

Kate visited a center for disadvantaged children in Harlem in Manhattan with New York City's First Lady, Chirlane McCray.

Obama and the Prince have met before - but never on the president's home turf. The last time the two met was in London.

The Duke of Cambridge flew first class on a shuttle flight this morning into Washington's Reagan National Airport. He will return to New York this evening to watch the Brooklyn Nets take on LeBron James and the Cleveland Cavaliers at the Barclays Center in Brooklyn.  

Prince William and Obama’s conversation could barely be heard above the clicking of cameras and reporters shouting questions, but the two could be seen laughing and smiling as the chatted.
