Highlights from Biden's town hall with voters in Philadelphia.
With less than three weeks to Election Day, Democratic nominee for president Joe Biden faced voters directly in an ABC News Town Hall from the National Constitution Center in Philadelphia on Thursday night.
The live special edition of "20/20" -- titled "The Vice President and the People" -- was moderated by ABC News Chief Anchor George Stephanopoulos.
The primetime event followed a fiery back-and-forth on the fate of the second presidential debate, which was originally scheduled for Thursday in Miami but ultimately canceled last Friday.
The nonpartisan Commission on Presidential Debates changed its format to be virtual following President Donald Trump's positive COVID-19 diagnosis, to which Trump took issue, saying he wouldn't "waste" time in a virtual debate. With Trump's rejection of the event, Biden then agreed to participate in the town hall with ABC News.
Voters had the opportunity to ask the former vice president the questions most important to them
The event was held in accordance with state and local government health and safety regulations, as well as guidelines set forward by health officials.
Trump, at the same time Thursday, participated in a town hall from Miami with NBC News. The president participated in an ABC News town hall in September.
Mieke Haeck, the mother of a transgender child, asked Biden how he would protect LGBTQ rights.
“I will flat-out just change the law. Eliminate those executive orders, number one,” Biden said.
Biden then brought up the high number of trans women of color who had been killed this year, and mentioned his late son Beau, who he said helped get the first transgender rights law passed in that state.
Voter Mark Halfman, who cast a ballot for Trump in 2016, described the president's foreign policy as a "modern-day miracle" citing his Middle East peace plan and reduction in troops overseas.
He asked Biden if the president deserved some credit, to which the vice president said, "a little but not a whole lot."
"We find ourselves in a position where we're more isolated in the world than we ever have been," Biden said. "'America first' has made America alone."
Biden cited Trump's relationship with questionable figures and hurting relationships with America's democratic allies.
"You see what’s happened and everything from Belarus to Poland ... to Hungary and the rise of the totalitarian regimes in the world. And as well as this president embraces all the thugs in the world," he said.
When asked about the environment, Biden reiterated that he would not ban fracking, calling instead for the practice to be managed "very, very well."
"I think you have to make sure that fracking is, in fact, not admitting methane or polluting the well or dealing with what can be small earthquakes and how they're drilling," he said. "So it has to be managed very, very well."
The former vice president also said that the future rests in renewable energy and criticized Trump for his comments on the environment.
"Every time we talk about global warming or the environment, the president thinks of, you know, it's a joke and I think it's jobs," Biden said.
"I, as president, am going to invest that $600 billion we spend on government contracts only on those things that, in fact, also are not only made in America, but building an infrastructure that's clean and new," he added.
Stephanopoulos pushed back on Biden, citing a New York Times op-ed written by a member of the Boilermakers Local-154, who said that fracking was at odds with Biden's goal to end the use of fossil fuels.
After touting the union's endorsement, Biden said that he would end oil subsidies. He also tried to distinguish between his plan and the Green New Deal.
"The new green deal calls for the elimination of all -- all nonrenewable energy by 2030," he said. "You can't get there. You're going to need to be able to transition, George, to be able to transition to get to the place where we invest in new technologies that allow us to do things that get us to a place where we get to net zero emission, including in agriculture."
Biden spoke about the current situation with the Supreme Court and didn't express confidence in Supreme Court nominee Judge Amy Coney Barrett's testimony this week.
"I don't even think she has laid out much of a judicial philosophy, in terms of the bases upon which she thinks are there unenumerated rights in the Constitution," he said.
Biden reiterated that her hearings and vote should not have been held this close to the election.
"You get disagreement among scholars on this, but I believe it's inconsistent, when millions of people have already voted to put someone on the court. I think it ... should have been held until ... this election is over.
Stephanopoulos asked Biden if he would consider expanding the Supreme Court, noting that a year ago during a primary debate he was against court packing.
Biden declined to respond, because he said he didn't want to distract from the biggest issues.
"No matter what answer I gave you, if I say it, that's the headline tomorrow. It won't be about what's going on now. The improper way they're proceeding," he said.
When pressed by Stephanopoulos, Biden said he will have a more clear position before Election Day, "depending on how (the Senate) handled this."
Biden encouraged voters, however, to use this opportunity to vote for leaders who can influence the courts.
"That's your opportunity to get involved in lifetime appointments that have. Presidents come and go, justices stay and stay and stay," he said.
