USA Today was first to report the cheating scandal in the District of Columbia.

Here is the follow-up story by Gregg Toppo, about the memo first leaked to John Merrow.

Eventually, the allegations were investigated by the DC Inspector General, who decided not to look at the erasure analysis or to interview many people. It was not the kind of full-scale investigation carried out in Atlanta by professionals. The DC Inspector General decided the cheating, if it happened, was not widespread.

This was confirmed by the Inspector General for the U.S. Department of Education.

But suspicions lingered, as did the cloud over the district, and the cloud refused to go away.
