Trump vs Harris Presidential Debate: Candidates go on attack in zinger-filled showdown

Trump has claimed ever since he first ran for president in 2015 that he would come up with a better health care plan than Obamacare.

However, when asked if he had come up with any new details for reform, Trump said he had "concepts of a plan."

"But if we come up with something, I would only change it if we come up with something that's better and less expensive and there are concepts and options we have to do that, and you'll be hearing about it in the not too distance future."

Evoking the chaos of the Jan. 6 insurrection was key to Harris' message on protecting democracy at the DNC and the same is true tonight. It could be a good strategy for her: Earlier this year, undecided voters in a 538/PerryUndem focus group told us Trump's actions on that day were one of their main concerns they had about supporting the former president.

"For everyone watching who remembers what January 6 was, I say we don't have to go back," Harris said. "And if that was a bridge too far for you, well, there is a place in our campaign for you," she added, alluding to the Republicans who've vocally supported her due to their disapproval of Trump's actions that day.

Trump defended his administration's role in negotiating with the Taliban in the U.S. withdrawal from Afghanistan and instead slammed the Biden administration for their handling of the final days of the war.

"We did have an agreement negotiated by Mike Pompeo, it was a very good agreement. The reason it was good, it was -- we were getting out. We would have been out faster than that, but we wouldn't have lost the soldiers, we wouldn't have left many Americans behind," he said.

ABC News' David Muir asked the vice president if she felt she bore any responsibility in the way the withdrawal in Afghanistan played out. Thirteen U.S. service members were killed in a suicide bombing at the Kabul international airport.

Harris started her response by defending the administration's decision to end America's longest war.

She then turned to criticizing Trump for the way he negotiated a peace plan with the Taliban that included a date of May 1, 2021, for the final withdrawal of troops -- which President Joe Biden then continued to carry out with a September deadline.
