The Israel-Hamas war is one of the most politically divisive issues for Democrats, and Harris has largely adopted President Joe Biden's stance on the issue in trying to balance unwavering support for Israel's security while also condemning the suffering of Palestinian civilians in Gaza.

"What we know is that this war must end," she said. "It must end immediately, and the way it will end is we need a cease-fire deal and we need the hostages. And so we will continue to work around the clock on that."

Fact Check: Mostly false

The Nord Stream 2 is an undersea pipeline that would have allowed Russia to increase natural gas exports to western Europe while bypassing Ukraine and depriving Kyiv billions of dollars in access fees. It’s true that in 2019, Trump announced sanctions that halted the pipeline’s construction. But by that point, the pipeline was nearly complete with a majority of the project occurring under Trump’s presidency, according to a 2020 analysis by the Congressional Research Service. Biden later waived sanctions against the pipeline’s builder at the request of Germany in 2021, but reimposed penalties the following year as Russia invaded Ukraine.

Trump refuted recent his recent remarks in which he appeared to accept he lost the 2020 election, including a comment that he "lost by a whisker."

"I said that?" Trump said.

"Are you now acknowledging that you lost in 2020?" ABC News moderator David Muir asked.

"No I don’t acknowledge that at all," he said. "That was said sarcastically."

Harris raised that she has the endorsement of more than 200 Republicans, including former Vice President Dick Cheney and former Trump staffers.

"If you want to really know the inside track on who the former president is, if he didn't make it clear already, just ask people who have worked with him," she said, noting that his former national security adviser said he is "dangerous and unfit."

Trump responded that he "fired most of those people."
