Prince William made his way to the White House on Monday, visiting with President Barack Obama in the Oval Office as part of Will and Kate's official visit to the US this week. While Kate stayed in New York for the first part of the day, William spent time in Washington DC to attend the International Corruption Hunters Alliance conference, making a stop at the White House to meet with the president. Prince William reportedly joked with Obama about Prince George's birth and the gender of royal baby number two, saying, "Last time, I remember when George was born, I forgot to actually work out if it was a boy or a girl. The excitement of the event and everything else was just chaos . . . It's going to be interesting next year. A busy year next year."
