Walz-Vance debate updates: VP candidates tangle on abortion, immigration and Jan. 6

Vance was asked if he would challenge this year's election results even if they were certified by every state leader. He did not rule it out.

Vance said he believed "we should debate about those issues peacefully in the public square."

Walz said that was "troubling."

"When this is over, we need to shake hands this election and the winner needs to be the winner," Walz said. "This has got to stop. It's tearing our country apart."

Childcare came up in the debate and Walz touted his state's paid parental leave and medical leave policies.

Walz said that the time offered to parents should be negotiable.

"We're saying is the economy works best when it works for all of us. And so a paid family medical leave program, and I will tell you, go to the families or go to the businesses and ask them, as far as child care on this, you have to take it at both the supply and the demand side," he said.

Vance agreed that parents need help, but stressed that they need more choices.

The senator then defended Trump's comments about child care not being expensive and focused on Trump's policies to cut taxes and bring jobs back from overseas.

"It's so expensive right now ... because you've got way too few people providing this very essential service," he said.

According to Mexican immigration officials, it is very uncommon for children to be used to smuggle drugs. However, the federal government has warned in the past of youth being used by drug cartels. Sources within the Mexican cartels consulted by ABC News in previous coverage say that their drugs are mostly being smuggled through regular points of entry by Mexican citizens with visas or by U.S. citizens.
