McCain Withheld Controversial Abramoff Email

On the stump, Sen. John McCain often cites his work tackling the excesses of disgraced lobbyist Jack Abramoff as evidence of his sturdy ethical compass.

A little-known document, however, shows that McCain may have taken steps to protect his Republican colleagues from the scope of his investigation.

In the 2006 Senate report concerning Abramoff's activities, which McCain spearheaded, the Arizona Republican conspicuously left out information detailing how Alabama Gov. Bob Riley was targeted by Abramoff's influence peddling scheme. Riley, a Republican, won election in November 2002, and was reelected in 2006.
