A new ad for Rep. Mo Brooks' Senate campaign released Monday uses audio from a shooting at lawmakers' baseball practice last month.

The ad, titled "Second Amendment," starts off with the audio, which includes the sound of shots being fired and people shouting, "Stay down!"

Words on the screen appear: "June 14: A Bernie Sanders supporter fires on Republican Congressmen. Mo Brooks gives his belt as a tourniquet to help the wounded. What's the liberal media immediately ask?"

The ad then cuts to video of the Alabama Republican being interviewed after the crisis.

"Congressman, does this change your view about the gun situation in America?" a reporter asks.

His edited version of his response: "The Second Amendment, our right to bear arms, is to ensure that we always have a republic. So no, I'm not changing my position on any of the rights we enjoy as Americans."

Last month, when James Hodgkinson opened fire on Republican lawmakers practicing for the annual congressional baseball game, Brooks and another person used his belt to created a tourniquet for Zachary Barth, a congressional aide who was one of the five injured in the attack.

Once he heard that the shooter was down, Brooks raced over to Rep. Steve Scalise. He held a cloth in place to stop the bleeding.

Scalise, shot in the hip, has been in recovery ever since.

Brooks is running in the special election for the seat currently held by Sen. Luther Strange. Strange was appointed to the seat vacated by Attorney General Jeff Sessions. The Republican primary is on Aug. 15.

Strange was endorsed by the National Rifle Association in May.

Brooks said the ad was created to show his strong support for the Second Amendment.

"We could think of no stronger response than being questioned by a reporter about my Second Amendment position after having come under fire by an assassin," he said in an interview with USA TODAY.

Still, the choice doesn't appear to be sitting well with Scalise's staff. Scalise's chief of staff, Brett Horton, wrote Monday on Twitter, "The day of the shooting, while waiting at the hospital, I avoided the news/audio/video as much as possible. This makes my stomach turn."

In response, Brooks said, "It makes my stomach turn also, but that does not change the truth of what happened."

Brooks also noted that he wished Scalise the best and a full recovery.
