The group is making a pledge to support a full repeal of the healthcare reform law, as well as opposing any bill or budget that includes funding or enforces any aspect of the law, a consideration in its endorsement process.

It's yet another indication that the group is keeping an eye on Senate Minority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellAlabama election has GOP racing against the clock McConnell PAC demands Moore return its money Klobuchar taking over Franken's sexual assault bill MORE's (R-Ky.) primary fight. The group said recently it was open to backing primary challenger Matt Bevin, and McConnell has so far refused to support efforts to defund ObamaCare.

Bevin picked up the endorsement of another conservative group, the Madison Project, on Monday.

"A lot of Republicans say they oppose Obamacare when they're campaigning, but few are actually willing to do what it takes to stop it," said Senate Conservatives Fund Executive Director Matt Hoskins in a release. "This new pledge is for those who are willing to fight Obamacare by supporting its repeal and also by opposing its funding."

The pledge comes as a handful of conservative Senators, led by Sen.

Lee insisted on Sunday his effort is not an attempt to shut down the government.

"We all know the government is going to get funded. The only question is if the government gets funded with ObamaCare or without it," said Lee on “Fox News Sunday.” "If we can delay it, we can stop its consequences, at least for now."
