Doc and Skip have uncovered new information that points to a 3rd gun involved in the Fast and Furious scandal. If this leads to the possibility of Attorney General Eric Holder lying about this weapon and evidence tampering, this could lead to impeachment. Also, a Mexican newspaper releases information that speculates the U.S. government worked in partnership with Mexican drug cartels and not only allowed billions of dollars worth of drugs into the U.S., but also supplied the cartels with weapons. Plus, the midterm election spotlight continues with a look at Texas, as Doc talks to Matt McCall and Dr. Robert Lowery running for Congress.
