FILE - In this July 6, 2011, file photo, President Barack Obama sits in front of a screen displaying a question he tweeted during a "Twitter Town Hall" in the East Room of the White House in Washington. President Obama is introducing a new hashtag to the fiscal cliff debate. The White House plans to promote (hashtag)My2K on Twitter and other social media — a reference to the estimated $2,200 tax increase that a typical middle-class family of four would see if the Bush tax cuts expire.
