The Senate Conservatives Fund, a group that has been wading more deeply into Republican primaries lately, on Monday added retired U.S. Air Force Col. Rob Maness (R) of Louisiana to the roster of candidates it is backing.

"Colonel Rob Maness is a constitutional conservative with a remarkable record of service to our country," Senate Conservatives Fund Executive Director Matt Hoskins said in a statement. "He understands the value of our freedoms and will fight to repeal Obamacare and stop the massive spending, bailouts, and debt that are bankrupting our country."
