The White House lifted its 40-year ban on photography during tours, and Instagram went crazy

On Wednesday, First Lady Michelle Obama posted this video to her Instagram account, lifting a 40-year White House ban on photography during tours:

"Guests are now welcome to take photos throughout the White House tour route and keep those memories for a lifetime," the White House said in a statement Wednesday. "Visitors are also encouraged to share their experience using the hashtag #WhiteHouseTour."

Sure enough, #WhiteHouseTour was soon trending on Instagram, and the world was treated to some seldom-seen images of one of the most iconic buildings in the world.
