U.S. Rep. Mo Brooks released his second Senate campaign ad on Monday, which called attention to the shooting at the congressional baseball practice last month in Virginia.

House Majority Whip Steve Scalise was one of five people who were wounded by gunfire in the June 14 shooting by James Hodgkinson, a former volunteer for Bernie Sanders' presidential campaign who was shot to death by Capitol Police.

Two member of Scalise's staff, however, appeared to take offense to the ad. One of Brooks' opponents in the GOP primary, state Sen. Trip Pittman, also released a statement criticizing Brooks.

In an interview Monday afternoon with AL.com, Brooks defended the ad.

"It is an ad that makes some people uncomfortable, including me, because it re-visits a very intense, horrific event," Brooks said. "But at the same time, anyone who watches that ad will not doubt my commitment to the Second Amendment right to bear arms."

Brett Horton, Scalise's chief of staff, tweeted that Brooks' ad "makes my stomach turn." Horton did not immediately respond to a message left Monday by AL.com.

"It makes my stomach turn, too," Brooks said. "But it's what happened and it's the truth."

Scalise spokesman Chris Bond told The Washington Post in an email, "I guess some people have their own ideas about what's appropriate, don't they?"

Scalise has been in and out of the hospital since the shooting, dealing with an infection in his hip related to the gunshot. In the most recent announcement on his condition from his office, Scalise underwent surgery July 13 for "management of deep tissue infection related to his bullet wounds."

"The ad released today by Congressman Brooks is disappointing," Pittman said in the statement. "I was shocked that he would agree to capitalize on the Alexandria tragedy for political gain. The video represents everything that is wrong in our political culture, where common decency is lost in the pursuit of votes at the ballot box."

Pittman also included his support of the Second Amendment in the statement but added, "we must be careful not to sensationalize tragic events."

The ad - which promotes Brooks' stance in supporting the Second Amendment, granting the right to bear arms -- opens with the sound of gunfire, which Brooks said was audio taken from a video of a passerby of the Capitol Police returning fire on Hodginkinson.

The ad also includes the detail that Brooks, who was at the practice, removed his belt to use as a tourniquet to assist one of the wounded.

The next screen states: "What's the liberal media immediately ask?" before flashing to a reporting at the site of the shooting asking Brooks, "Does this change your views on the gun situation in America?"

In the ad, Brooks responds, "The Second Amendment, the right to bear arms, is to help ensure we always have a republic. So, no, I'm not changing my position on any of the rights we enjoy as Americans."

Brooks also discussed his views on the Second Amendment in an interview with AL.com following the shooting.

In defending his ad, Brooks pointed to campaign ads from Senate opponent Luther Strange advocating his support for the Second Amendment.

"Bear in mind the circumstances," Brooks said Monday. "Luther Strange is running unending numbers of ads about his support for the Second Amendment. I think this ad very concisely and effectively shows my support for the Second amendment right to bear arms in a very real way. When the media within minutes of the shooting challenges me on whether I still support the Second Amendment, I very candidly and forthrightly in a heartfelt way said yes, I do.

"And that's not a contrived statement. That is a real life statement after having been through a gun battle when over a hundred shots were fired while unable to defend myself because of Washington D.C.'s restrictive gun laws that prohibit me from carrying the Glock pistol that I own."

Two days after the shooting, Brooks confirmed that his name was included on a list of apparent Congressional targets found on Hodgkinson.
