Ted Stevens died a little more than a year ago, but the aftershocks of his corruption case continue to make the news.

It was not recommended that charges be filed against the special prosecutor who was investigating the late Senator from Alaska, according to USA Today.

An investigation of the prosecutor did, though, find significant, widespread and at times intentional misconduct, the paper reported.

According to the report, which followed a two year investigation, the prosecutor concealed evidence that could have been used to defend Stevens, according to the Associated Press. The reason charges aren't being filed, The New York Times reported, is that the judge overseeing the trial never officially ordered the prosecutors to turn over evidence in compliance with the law.

The original charges against Stevens related to his allegedly lying on disclosure forms about a gift he received from an oil-field services firm, according to The Times. Following being convicted of these charges in 2008, Stevens lost his reelection bid.

When evidence of the misconduct came out, Stevens' convictions were vacated; he died in a plane crash in August of 2010.
