Helmer made headlines earlier this month after releasing a video of him purchasing an assault weapon at a gun show to show how easy it is for anyone to buy a high-powered weapon in the United States.

Helmer also captured attention back in September for calling out Comstock with a “Top Gun” parody campaign ad where he accused the Republican lawmaker of moving too far to the right and not holding town hall events. In a parody of the iconic bar scene from the movie, Helmer took on the role of Tom Cruise's "Maverick."

“I’m different. I’m not a politician," Helmer, an Army veteran who served in Iraq and Afghanistan, says in the new ad. "I’m a Rhodes scholar who served in combat. I’m for a Medicare-for-all option and against drug companies that rip off seniors. I'll fight the gun lobby to protect children, not guns.”
