A new online advertisement from U.S. Sen. Mitch McConnell's reelection campaign focuses on the targeting of conservative groups by the IRS—an issue the campaign says it's not going to let slip out of the public discourse.

The nearly three minute ad uses speeches from McConnell on the IRS issue before it became a national controversy, as well as media reports and testimony from IRS officials to Congress.
