Both the former IRS commissioner who was in charge when the agency singled out some conservative groups for extra scrutiny and the man who replaced him will be appearing at a Senate Finance Committee hearing Tuesday morning.
Douglas Shulman, an appointee of President George W. Bush who left the IRS last November, and acting commissioner Steven Miller (who is losing his job because of the scandal) are due at the 10 a.m. ET hearing.
There is word of another controversial leak investigation by the Department of Justice. The target is Fox News reporter James Rosen, who was monitored by the department after breaking a story about North Korea's nuclear weapons program in 2009.
