(CBS) -- Prince Harry arrived in Washington on Thursday for the start of his seven-day, six-city tour of the United States.
The 28-year-old British royal toured an exhibition about land mines, a cause dear to his late mother, Princess Diana, to open a weeklong U.S. visit devoted to the wounded victims of war.
For the prince, the tour in the halls of Congress was a world away from the Afghanistan war zone where he recently served for 20 weeks in an attack helicopter. It was just as far removed from his hijinks in a Las Vegas hotel room last year, when fuzzy photos got out of a naked Harry playing strip billiards.
One of America’s most storied wounded warriors, Republican Sen. John McCain, escorted Harry at the exhibition.
On Friday, the prince is scheduled to visit Arlington National Cemetery, where he’ll lay a wreath at the Tomb of the Unknown Soldier, and a military hospital in Maryland before flying to Colorado for the 2013 Warrior Games.
He’s also set to visit New Jersey and New York on Tuesday, and will play in a charity polo match on Wednesday in Greenwich, Conn.
