Here at the White House, we're dedicated to making President Obama's administration the most open and accessible in history. That's why, for the second year in a row, we thought it'd be a gouda idea to brie-unite a certain cast of characters to help us bring back a tradition that dates back to the days of President Andrew Jackson.

On February 22, 1837, President Jackson had a 1,400-pound block of cheese hauled into the main foyer of the White House for an open house with thousands of citizens and his staff, where they discussed the issues of the day while carving off slabs of cheddar.

This year, we aim to do even feta. On Wednesday, January 21, in fromage to President Jackson (and to President Bartlet, if you're a fan of The West Wing), we're hosting the second-annual virtual Big Block of Cheese Day, where members of the Obama administration will take to social media to answer your questions about the President's State of the Union address and the issues that are most important to you.

Log on to Twitter, Facebook, Instagram, and Tumblr, and ask away using the hashtag #AskTheWH. We'll do our best to answer as many questions as we can.

So be sure to visit WhiteHouse.gov/SOTU to watch the State of the Union address on January 20, 2015 at 9 p.m. ET and check out the schedule of all the ways you can engage on the following day, January 21. We camembert to think you'd miss it.

All day:
