McConnell attacked from the right?

A conservative group is launching a radio ad challenging Senate Republican leader Mitch McConnell to refuse to fund President Barack Obama's health care law even if it means triggering a government shutdown.

The Senate Conservatives Fund is spending nearly $50,000 on the ad that will begin airing on Tuesday in Kentucky. The ad calls on McConnell to lead the fight on the issue that has divided Republicans.

The Associated Press obtained a text of the ad in advance.

The Senate Conservatives Fund is an organization that was founded by former South Carolina Sen. Jim DeMint. It has been running similar ads pressing other Senate Republicans on the issue.

The group said in July that it would be open to backing McConnell's GOP primary challenger, Matt Bevin.
