White House officials took questions Wednesday from all across the nation via Twitter, Facebook, Instagram and Tumblr on the heels of the State of the Union address. It's an effort called Big Block of Cheese Day, which was inspired by an event that took place at the White House back in 1837 that involved a lot of cheese.
On February 22, President Andrew Jackson hosted an open house in the main foyer of the White House where his staff and thousands of citizens feasted on a 1,400-pound block of cheese while they discussed the issues of the day.
NBC's political drama, "The West Wing," paid tribute to President Jackson's act of populism in its first season.
Obama has turned the event into a tradition. Back for the second year in a row, "The West Wing" cast reunited to help promote the online town hall.
