A super PAC supporting Donald Trump released a new ad Monday that seeks to use the Orlando nightclub shooting to make the case for his presidency.

Officials with Great America PAC say they will spend about $700,000 to air the 60-second ad on cable programs nationally and in 10 battleground states. It will air for a little more than three weeks.

The ad, entitled The Enemy, features former Navy SEAL Carl Higbie, who says the nightclub shooting is a reminder that the fight against terrorism has come to U.S. shores. “Join millions of active duty military members and veterans like me who stand with Donald Trump,” he says.

Great America PAC is one of several independent groups scrambling to become the main independent vehicle supporting Trump’s bid. Eric Beach, the PAC’s top fundraiser, said the group raised about $1 million in May. The super PAC is scheduled to file its monthly fundraising report with the Federal Election Commission later today.

Other organizations have cropped up to back Trump’s candidacy, including a new group called, Rebuilding America Now, aligned with a longtime Trump associate, California businessman Tom Barrack. Earlier this month, Barrack said the group had secured $32 million in pledges from donors.

CNN first reported on the new ad from Great America PAC.

As Trump's allies compete to position themselves as the leading super PAC backing his candidacy, Clinton and the main super PAC supporting her have pummeled Trump with ads that argue he's unfit to hold the presidency.

Clinton and her main super PAC, Priorities USA Action, have aired nearly 4,900 local TV spots in the last 10 days, according to Media Monitors, which tracks advertising in local markets. Trump's campaign ran no advertising during that period in the markets the group examined.
