Prince William's wife, Kate, has toured a child development center with New York City's first lady.

The Duchess of Cambridge shook hands with Chirlane McCray before both entered the Northside Center for Child Development in Harlem on Monday.

The two spent about an hour at the center. It provides educational and mental health services to about 3,300 children and families each year.

Kate was greeted with cheers from a crowd of several dozen spectators standing behind police barricades across the street.

Meanwhile, Prince William went to Washington to meet with President Barack Obama at the Oval Office and discuss illegal wildlife trafficking.

It's the royal couple's first visit to the U.S. since 2011.
