Democrats are starting to join in the outrage over the Internal Revenue Service's targeting of conservative groups.

Monday morning, Senate Finance Committee Chairman Max Baucus (D-Mont.) and Sens. Tim Kaine (D-Va.) and Joe Manchin (D-W.Va.) all issued statements denouncing the IRS and calling for an investigation and corrective action.

“These actions by the IRS are an outrageous abuse of power and a breach of the public’s trust. Targeting groups based on their political views is not only inappropriate but it is intolerable," Baucus said, adding: "The IRS will now be the ones put under additional scrutiny.”
