IRS SCANDAL: Watchdog to IRS: Quit killing conservatives with paperwork.

President Barack Obama maintains there’s “not even a smidgen of corruption” in the Internal Revenue Service’s targeting of tea party and conservative groups, that it was just the result of “bone-headed decisions” by low-level IRS technocrats.

But testimony at a congressional hearing last week raised red flags about IRS abuse of conservatives that should trouble Americans no matter what their political leanings. . . .

In 2012, then IRS commissioner Doug Shulman told Congress there had been no targeting of tea party groups even though we now know it had been going on since 2009. “The last time I checked, lying to Congress is a felony,” Mitchell said.

Confidential donor information about several conservative groups, including the National Organization for Marriage, the Texas Public Policy Foundation and the Republican Governors Public Policy Council, were leaked to their political foes or the public. “That is a crime,” she noted.

And Mitchell pointed to the elephant in the room in the IRS controversy: former IRS executive Lois Lerner invoking her Fifth Amendment right against self-incrimination before the same subcommittee. “She apparently knows of criminal acts involved in this scandal.”

Indeed.
