In the 30-second ad, titled "Presidential," Priorities USA, the largest super-PAC supporting presumptive Democratic nominee Clinton for president, rehashes controversial statements Trump has made throughout his campaign. 

"I know more about [the Islamic State in Iraq and Syria] ISIS than the generals do, believe me," Trump says at a rally shown in the ad.

"I'm really good with war. I love war, in a certain way," Trump says.

The ad ends: "Donald Trump, too dangerous for America." 

The spot will air in eight swing states, including Iowa and Nevada, as part of a multimillion-dollar general election ad buy. It was previewed exclusively on NBC’s “Meet the Press” on Sunday.

“Donald Trump brags about consulting himself on national security issues, says he loves war and claims to know more about ISIS than the generals do. These are disqualifying statements for someone who wants to be commander in chief and proof that Donald Trump is too dangerous to ever be President of the United States,” Justin Barasky, communications director at Priorities USA, said in a statement. 

That ad follows two released by the Clinton campaign last week that highlight her focus on children and family issues. 

Meanwhile, Trump is struggling to get ads on the air, according to a fundraising email he sent to supporters on Saturday. 

In it, the campaign asked for donations so it could raise at least $100,000 by the end of the day. 

"Right now we're facing an emergency goal of $100,000 to help get our ads on the air," the email said.

"Crooked Hillary is about to invade your TV with ads attacking Mr. Trump. But we're prepared to fight back," it read, adding that the campaign plans to attack Clinton over her role in Benghazi and the FBI probe into her use of a private email server while secretary of State.
