An investigation began Wednesday into whether or not any copies of Mitt Romney's tax returns were taken by an anonymous hacker. A letter was sent to a Romney political office where a one million dollar "ransom" was demanded to keep the tax returns from being released to the public. PricewaterhouseCoopers the firm that holds Romney's accounts has stated that there is no evidence to suspect that the files have been tampered with, or that the system was compromised. While an investigation has begun there is no way to know whether or not these claims are true.
