Jon Huntsman is being trailed by a film crew in China

As he considers a 2012 bid, Jon Huntsman has been allowing a camera crew film him in various settings during his day job as President Obama's ambassador to China. It's unclear who's backing the project, but Reuters reports the filming has been happening on and off for the past year.

"The privately funded project ostensibly plans to make a documentary about Huntsman, although it would undoubtedly come in handy in any political campaign," Reuters notes.

Huntsman and other U.S. officials declined to comment on the story.
