Investigate the use of donations to the Red Cross

The New York Times has reported that the Red Cross has been seen only on occasion in the Rockaways and other hard-hit areas the two weeks following Hurricane Sandy, despite collecting $150 million from donations for storm relief.
Red Cross has admitted that most of the money is merely going into their coffers to be used for whatever purpose they deem necessarily, despite misleading commercials implying the money is for storm relief. Apparently, it has not deemed Sandy, Katrina or the disaster in Haiti necessarily; most of the money raised each time was just stored away.
This is not merely dropping the ball; it looks like fraud. I am asking that a formal inquiry into the Red Cross is opened to assure that the organization we donate our money to is as transparent as possible.
