Britain’s Prince William meets President Obama in the Oval Office, during a visit to Washington, DC.
The two men chatted amiably while reporters and photographers snapped pictures. Members of the media were ushered in and out of the room in less than two minutes. Obama and William did not make any formal remarks.
The Duchess of Cambridge arrived in New York City and visits the Northside Center for Child Development in Harlem on Monday.
The centre provides mental health and educational services to families living in high-risk neighbourhoods.
Kate, who is pregnant with their second child, remained in New York and was not present for William’s meeting with President Barack Obama at the Oval Office.
The Duke and Duchess of Cambridge, as they have been officially known since their 2011 wedding, are visiting NYC at a time when the city is facing a nightly series of street protests against police violence.
The demonstrations, which have featured brief blockades of intersections and bridges, could disrupt traffic during the visit and may raise new security concerns even though there has been no major violence so far in New York.
The royals are also set to venture into Brooklyn for a National Basketball Association game between the Brooklyn Nets and the Cleveland Cavaliers at the Barclays Centre.
At least one protest is already planned to coincide with the game. A Facebook event page titled “Barclays Stadium, SHUT IT DOWN,” has 83 people saying they would attend the rally in the borough.
On Tuesday the royals, who are expecting a second child in April, will tour the National September 11 Memorial and Museum, including its reflection pools.
Dignitaries including former Secretary of State Hillary Rodham Clinton and daughter Chelsea, a new mother herself, are expected to meet the couple.
They will cap their visit by attending a fundraising dinner at the Metropolitan Museum of Art on Tuesday night to benefit the University of St. Andrews in Scotland, where the couple met and earned their college degrees.
