The matchup could have an impact on critical undecided voters.
Vice presidential candidates Gov. Tim Walz and Sen. JD Vance squared off for the first and only time this election season.
Unlike the last two presidential debates, the candidates appeared to be more cordial. However, both running mates criticized the presidential candidates on a host of issues including gun violence, reproductive rights, immigration and climate change.
Walz appeared to have nerves in the opening of debate, but went on the attack as the night went on. Vance took aim at Harris and her policies and pushed Trump's policies.

In response to Vance's criticism of Harris' immigration policy, Walz brought up the fact that Congress had a plan to address the migrant issue before Trump pushed Republicans to drop their support.
"Pass the bill, she'll sign it," Walz said.
Claim: Walz: 'The person closest ... to Donald Trump, said he is unfit for the highest office. That is Senator Vance.'
Fact Check: True
Vance has shifted his view toward President Trump since he first rose to prominence. Early in his career, Vance made a number of comments that were disparaging toward Trump. The specific comment that Walz seems to be referencing here is from a 2016 New York Times op-ed written by Vance ahead of the release of his book "Hillbilly Elegy." In the op-ed, Vance wrote that "Mr. Trump is unfit for our nation's highest office." In years since the op-ed was published, Vance has said his views on Trump changed.
Vance was pressed on his proposal to mass deport immigrants.
The senator argued that it was time to "stop the bleeding" contending Harris' policies have allowed for more criminal activity.
He maintained that the first deportations should be those with criminal histories and the country should go back to Trump's border policies.
Asked about climate change's role in extreme weather amidst the aftermath of Hurricane Helene, Vance said Trump supports clean air and water, but expressed skepticism carbon emissions play a role in such weather events.
Vance's comments come one day after Trump bluntly denied any connection between climate change and the devastating storm.
Walz, meanwhile, emphatically said during his response: "Climate change is real."
