LOUISVILLE, Ky. (WDRB) -- Republican Matt Bevin has some harsh words for U.S. Senator Mitch McConnell in a new campaign ad.

"After 30 years in Washington, voting for one bailout after another, slinging mud is all Senator McConnell has left," the ad states.

The ad began airing on Wednesday. In it, Bevin talks about McConnell's support for private-sector bailouts. This is in response to a McConnell campaign ad that accused Bevin of having a history of tax delinquency, which Bevin denies.

It also accuses McConnell of using mudslinging campaigns, and compares them to President Obama's campaign ads.

Bevin is challenging McConnell in next year's GOP primary.

McConnell is also facing Democratic opposition from Kentucky Secretary of State Alison Lundergan Grimes.
