Mark Kelly, the husband of former Rep. Gabrielle Giffords (D-Ariz.), is threatening to back an election challenge against Sen. Jeff Flake if the Arizona Republican votes against legislation to expand background checks.
At a Christian Science Monitor breakfast on Tuesday, Kelly said he would back an opponent to Flake if the "right candidate" was available and if the senator failed to support a background check bill, according to reports.
"You know, friendship is one thing," Kelly said. "Saving people's lives, especially first-graders, is another thing."
Kelly's comments came after Flake said he planned to vote against background check legislation in a statement on his Facebook page.
"A lot of senators are looking for a reason just to get to 'no,' " Kelly added. "I experienced this personally last night when shown the Facebook posting of Sen. Jeff Flake, Gabby's good friend. He posted that he intends to vote ‘no’ on this legislation."
Kelly also said that if lawmakers "won’t stand up and do what the American people are asking, we will be there to replace them," according to reports.
Giffords was shot in the head during a constituent meeting in Tucson, Ariz., in early 2011.
Since leaving office, Giffords and her husband have become strong advocates for tougher gun control legislation. They founded Americans for Responsible Solutions, a political action committee they say will back pro-gun-control lawmakers and counter the muscle of the National Rifle Association.
Giffords and Kelly plan to raise $20 million in time for the 2014 midterms, but have not yet set any lawmakers in their sights.
Americans for Responsible Gun Solutions is also looking to collaborate with the PAC funded by New York City Mayor Michael Bloomberg, Independence USA, which played a pivotal role in helping Rep. Robin Kelly (D-Ill.) win a recent House special election.
Kelly suggested that Flake may not yet have “read the bill” drafted by Sens. Joe Manchin (D-W.Va.) and Pat Toomey (R-Pa.), which would expand background checks to all gun show and Internet sales.
Kelly said he would talk to Flake personally later, and hoped he could change the senator's mind.
"I think we can get him to come around," Kelly said.
