Yes, the DoJ was involved in the IRS corruption;

somebody give me a reason to trust ANY of these people.
A federal judge has broken loose more emails that the DOJ had surely hoped would never surface. The picture it reveals isn’t pretty. The documents prove that Lois Lerner met with DOJ’s Election Crimes Division a month before the 2010 elections.

It has to be embarrassing to the DOJ, which may not be the most impartial one to be investigating the IRS. In fact, the DOJ withheld over 800 pages of Lerner documents citing “taxpayer privacy” and “deliberative privilege.” Yet these internal DOJ documents show Ms. Lerner was talking to DOJ officials about prosecuting tax-exempt entities (yes, criminally!) two years before the IRS conceded there was inappropriate targeting.
