Vice President Biden's handlers appear to be going to new lengths to keep their boss' antics and open-to-interpretation quips from spiraling out of control in the 24-hour news cycle. 

The close attention to the vice president's style and coverage comes after Biden set off a round of campaign crossfire over his comment that Republicans want to put people "back in chains." Pressed anew on whether President Obama might consider dropping his No. 2 in favor of, say, Hillary Clinton, the White House is standing by the vice president. 

Press Secretary Jay Carney said that decision was made "a long, long time ago" -- which could explain why media coverage of Biden has been so tightly regulated lately, as aides try to prevent an off-the-cuff moment from dominating the day.  

Fox News was told that during the vice president's last campaign swing through Virginia, the one that included the infamous "chains" remark, Biden's office tried to edit pool reports that a small group of journalists put together for the rest of the media.
