This is What's Trending Today...

The White House is officially on Snapchat. The announcement came ahead of President Barack Obama's final State of the Union address on Tuesday night.

Followers of the White House Snapchat will get a behind-the-scenes look at the final preparations before Obama's speech. The White House is also streaming the State of the Union on YouTube and, for the first time, on the Amazon website.

The White House said in a blog post that the Snapchat account adds to its social media presence. The blog said it was part of the administration's strategy of "meeting people where they are" and providing Americans with a "multitude of ways to engage with their government."

Snapchat has 100 million daily users.

Snapchat also has an official #SOTU -- or "State of the Union" -- live story. Fellow politicians have tweeted about taking part in the live story:

Snapchat is a mobile application that permits users to receive photos and videos that disappear after they are viewed. However, the White House's Snapchats cannot legally disappear. Government rules require presidential administrations to keep official records.

That means all White House snaps will be preserved for history.

And that's What's Trending Today.
