A true piece of unbiased journalism is very hard to come by.I'm not a Huffington Post reader, but aren't they one of the news outlets typically mentioned when people talk about biased journalism? If that's the case, you have to take anything coming out of their pages with a huge grain of salt.
If there's a problem, the FTC will come down on them and we'll know. A quick google doesn't show an article with any kind of "smoking gun" from a source other than the Huffington Post or some form of watchdog group (with, presumably, an axe to grind).
