@POTUS joins Twitter, jokes with @BillClinton

New York (CNN)The bear is loose... on Twitter.

So, it's official. After years of signing "-BO" at the end of @BarackObama to signal the tweets he crafted himself from an account operated by the Organizing for Action staff, the President now has his very own handle @POTUS, tweeting for the first time:
"Hello, Twitter! It's Barack. Really! Six years in, they're finally giving me my own account."
    And some asking the question on a lot of people's minds, what happens to the handle when a new President takes office?
    According to a White House official, @POTUS handle will transfer to the next President when Obama leaves office on 2017. President Bill Clinton even had some fun with the news, tweeting: Welcome to @Twitter, @POTUS! One question: Does that username stay with the office? #askingforafriend

    For his banner photo, the President chose a powerful image from the 50th anniversary of the Selma to Montgomery marches, where he, first lady and Congressman John Lewis (D-Georgia) led a commemorative march, hand in hand, over the Selma Bridge.
    Per a statement from the White House, the @POTUS handle "will serve as a new way for President Obama to engage directly with the American people, with tweets coming exclusively from him."
    Naturally, folks on social are having a little fun with this new presidential social presence:

    In the meantime, we'll just wait for your first GIFs and selfies, Mr. President.
