British Royal Couple Arrives in New York

Britain's Prince William, Duke of Cambridge, and his wife Catherine, Duchess of Cambridge, arrive at the Carlyle hotel in New York, Dec. 7, 2014.

Britain's Prince William meets Monday with President Barack Obama at the White House. The future king of England is expected to talk with the president about the illegal wildlife trade.

After his meeting with Obama, William will deliver a major speech at the World Bank International Corruption Hunters Alliance Conference in Washington.

He is expected to say the illegal trade in elephant tusks, rhino horns and other animal parts is "one of the most insidious forms of corruption and criminality in the world today," and those "who look the other way or spend the illicit proceeds of these crimes must be held to account."

Prince William will also point out that some animal parts are literally worth more than their weight in gold.

William, his wife Kate and his brother Prince Harry are the founders of Britain's United for Wildlife charity.

Britain's popular royal couple arrived in New York Sunday for their three-day U.S. trip. It is the first time either of them has been to New York.

While William is in Washington Monday, Kate and New York City's first lady Chirlane McCray will visit a clinic that provides mental health services for impoverished children.

Later Monday, the royal couple will go to Brooklyn's Barclays Center to see their first National Basketball Association game, featuring LeBron James and the Cleveland Cavaliers against the Brooklyn Nets.

The NBA said William and Kate are attending the game as part of a new partnership between the league and the Royal Foundation. The new project will unite NBA players and England's royalty to stress global wildlife conservation, develop a new generation of conservation leaders and boost the sport of basketball.

The royal couple's visit will include some events with other high-profile guests.

Former U.S. Secretary of State Hillary Clinton and daughter Chelsea are accompanying William and Kate to a New York reception highlighting conservation efforts.

At a black-tie scholarship fundraiser for Scotland's University of St. Andrew, other guests are expected to include actor Tom Hanks and opera singer Renee Fleming. Tickets for the event were expected to sell for up to $10,000. William and Kate - the duke and duchess of Cambridge - are graduates of St. Andrew.
