This Jan. 10, 2015 photo shows the dining room at the Morris-Jumel Mansion in New York. President George Washington hosted a dinner party here for his cabinet in 1790, including Secretary Treasurer Alexander Hamilton, Secretary of State Thomas Jefferson and Vice President John Adams. Washington used the mansion for his military headquarters in 1776. A new musical, "Hamilton," has just opened off-Broadway in New York, using hip-hop and history to tell the story of Hamilton's rise from immigrant orphan to Washington's right-hand man.
