The video ad above was put together by VoteVets.org, and is currently running on various social media. It asks viewers to contact Republican Senator Jeff Flake of Arizona and urge him to support universal background checks for all firearms. Glenn Kunkel, an Iraq War veteran who received two Purple Hearts during two tours of duty, is featured in the ad firing an AR-15 at a water-filled mannequin.

Kunkel says:

"I had to pass a background check to join the Marine Corps, before I could carry a weapon similar to this one in Iraq. Here at home, anyone can purchase this weapon, no questions asked."

"I support the Second Amendment, but we've seen what can happen when these fall into the wrong hands."

"I needed a background check to carry similar weapons in combat. We should require the same here at home. Call Senator Flake and tell him to support Universal Background Checks."

VoteVets says there are other versions available for other Senators, as well.

The U.S. Senate is set to vote on universal background checks in early April, and despite the fact that 92% of Americans support the measure, its passage remains in doubt. Watch VoteVets video ad, and tell your Senators that you support universal background checks.
