The source who leaked Romney’s 47% speech is threatening to leak his tax returns. How serious are these threats? Nobody knows.
Romney is a rich man. I don’t care how he made his wealth so long as he abided by the laws as they stand on the books. Every indication is that he did obey all of the laws or else the IRS would have been after him. And if he made money in "unfair" ways, it would be because the laws favored investment in that way. Big deal.
Very little is known about the source who leaked the video of Romney’s fundraiser, so the credibility of the new threat is unclear.
Anne Onymous appears to be primarily concerned with the clip of Romney talking about his visit to the Chinese factory. A Google + page for the user Anne Onymous, which uses the same picture as the YouTube channel and the Twitter user, describes the user as living in Dongguan, China, and working at Global Tech Appliances, Inc., the company that owns the factory Romney is reported to have visited.
