Retracted via twitter hey? Not enough guts to do it in front of the camera. Typical, sleazy whiny grumpy liberal.
I cannot believe (well, this is MSNBC) any opinion/news program would use a single source as the basis for a report without some type of confirmation, although this has become standard practice by numerous Left Wing cable and broadcast outlets (see Media Matters).
This is an excellent example of how biased and dangerous many in the MSM are. If a story, real or not, fits the agenda, run with it. This is straight out of the Dan Rather school of reporting.
