The Senate Conservatives Fund just spent $340,000 on a new ad-buy campaign urging Senate Minority Leader Mitch McConnell (R-KY.) to take the lead in a push to defund Obamacare.
"McConnell is the Senate Republican leader but he refuses to lead on defunding Obamacare," the voiceover in the new ad says.
The ad, which was unveiled on Thursday, will air from Friday through September 17, according to National Journal.
The Senate Conservatives Fund has targeted a number of lawmakers urging them to demonstrate stronger opposition to opposing the Obama administration's healthcare reform law. In August the Senate Conservatives Fund, which was previously associated with former Sen. Jim DeMint (R-SC), launched a statewide campaign in Kentucky meant to make McConnell "feel the heat" on defunding Obamacare.
