The 60-second ad, by Great America PAC, features Dorothy Woods, the widow of Ty Woods, an American killed in the 2012 terrorist attack in Benghazi, Libya.

It's part of a $2 million ad buy from the group to help Trump, the GOP presidential nominee, in the coming weeks nationally and in battleground states, CBS News reported. It will also air Thursday night during presumptive Democratic presidential nominee Hillary ClintonHillary Diane Rodham ClintonWatergate’s John Dean: Nixon would tell Trump 'he's going too far' Senate Homeland Security chairman requests briefing on Ivanka Trump emails House GOP to hold hearing into DOJ’s probe of Clinton Foundation MORE's speech at her party's convention.

In the ad, titled "The Difference," Woods says her husband was a "fierce patriot."

"He was killed during the attack in Benghazi while saving American lives under the charge of our State Department," she says.

"When Hillary Clinton was challenged by Congress on who was to blame for the attack, her response was a disgrace."

The ad then shows Clinton speaking in 2013 during the Senate Foreign Relations Committee hearing on the attack.

"The fact is, we had four dead Americans. Was it because of a protest or was it because of guys out for a walk one night who decided that they’d go kill some Americans?" she said. "What difference at this point does it make?"

"The difference," Woods says in the ad, "is while most families are reunited, some make the ultimate sacrifice. The difference is having accountability. The difference is being truthful to the American people."

Woods goes on to say that Americans need a leader whom they can trust and who will have their backs. 

"That leader is Donald Trump," she says.
