The night before Alabama's Senate runoff, Republican candidate Roy Moore pulled a gun out of his pocket at a campaign rally.

Per a video of the Monday rally, the former Alabama chief justice said false ads had said he didn't believe in the Second Amendment.

"Nearly three months of negative ads that we couldn't answer with money because we didn't have it," he said. "Ads that were completely false, that I don't believe in the Second Amendment."

He then paused before pulling the gun out.

"I believe in the Second Amendment," he said, leading to cheers from the crowd.

Moore is facing Sen. Luther Strange in Tuesday's Republican runoff for the nomination. The race to fill the seat vacated by Attorney General Jeff Sessions has become divisive for conservatives, with Moore running a campaign targeting "the establishment" in Washington, D.C.
