California State Sen. Ron Calderon is hinting at his defense on corruption charges, and the senator laid it out in a Tweet.

Calderon, a Democrat, faces federal charges for allegedly accepting $100,000 in bribes for friends and family in exchange for pushing certain bills, but last night he sent out via his Twitter account a picture of a Daily Journal article.  

In that article defense attorney Edward J. Loya of Los Angeles, and who has also served as a U.S. Department of Justice prosecutor, suggest the case against Calderon seems weak.  

The primary reason given by Loya is the credibility of the government's star witness, Michael Drobot, who Loya says was involved in his own legal trouble.
