The latest newest news on the D.C. forefront: the 40-year-old ban of photography during public tours of the White House has just been lifted. To celebrate this exciting news, Michelle Obama took to Instagram and Twitter as her team posted a video announcing the removal of the ban.

Using #WhiteHouseTour, the newest photos from people that were on the tours have been flooding Twitter. Ironic enough, the ban is supposed to allow people to capture their memories as they walk through the iconic halls of the White House, but, instead, people opted out to take the ever-so-famous selfie. It's no surprise that this will now be a trending thing to do while roaming the hallowed halls of the White House. Twitter user, CubbyGraham, took to Snapchat to document this historic event, as he posted photos and live videos to his Snapchat Story of him on the tour. He even caught a glimpse of POTUS taking off in a helicopter. Making a great start to the selfie trend, he posted these photos to his Snapchat feed for the world to see.

Originally, the ban was put into place years ago to preserve any old artwork that could have been damaged by old flash photography said the Office of the First Lady. The exact date of when the rule was in effect is unclear. However, there are changes in flash photography that led to the ruling being lifted.

Tourists were welcomed with open arms as they walked into the White House earlier yesterday.

"I'm gonna share this with everybody," said Thomas Auanger, a visitor from Texas, after taking a selfie with his 7-year-old son, Jack, in front of a portrait of Ronald Reagan.

"I've taken pictures of every single thing since the first lady said we could," said Shari O'Connor, who was visiting from Boston.

As many people posted to Instagram and Snapchat using the trending hashtag as mentioned above, here as some of the historic photos taken from yesterday.

The First Dogs, Bo and Sunny, cracked a smile as they managed to get into a few of the photos as well.

While you may be quick to take out your Nikon DSL or your selfie-stick to snap a moment, there are a few restrictions to this new law. According to Reuters, video cameras, cameras with detachable lenses, tablets, tripods and monopods are strictly prohibited. Only phone cameras and compact still cameras with a lens no longer than 3 inches (7.6 cm) are allowed, the White House said. Various precautions are being taken as this rule is set into action: sharp metal points will be bolted to the top of the black iron fence as a temporary measure until authorities can set up a more permanent tactic next year.
