1st presidential debate between Trump and Biden spirals into chaotic clash

When asked by Wallace if he believes that human pollution and greenhouse gas emission contributes to global warming, Trump responded that, “I think a lot of things do, but I think to an extent, yes.”

“I want crystal clean water and air,” Trump said. “I want beautiful clean air.” 

But Trump has previously publicly said he isn't sure how much humans affect the climate. He also pulled the United States out of the Paris Climate Agreement.

Biden, on the other hand, has said he would recommit to the Paris Climate Agreement. He also said if he was elected in November, he would aim to have the U.S. reach zero emissions by 2050.

Wallace went on to press Biden on the cost of his climate change plan noting it includes upgrading 4 million buildings and weatherizing 2 million homes over four years. Biden said the plan will create millions of good jobs and drew the distinction that the Green New Deal is not his plan. 

"We're going to be in a position where we can create, hard, good jobs by making sure the environment is clean, and we all are in better shape," Biden said.

Biden, invoking his late son Beau, raised reporting in The Atlantic that Trump called military members "losers" and "suckers," but Trump used it as a chance to bring up Biden's other son, Hunter.

"I don't know him," Trump said of Beau, before attacking Hunter's history with drug addiction.

"That is not true," Biden said. "My son, my son, like a lot of people you know at home, had a drug problem. He has overtaken it. He's fixed it. He's worked on it and I'm proud of him. I'm proud of my son. He wasn't given tens of millions of dollars. That is totally discredited."

Asked if he would be willing to denounce white supremacists, Trump said he would be willing but skirted around making the statement. 

"Sure. I'm willing to do anything. I want to see peace," Trump said. "What do you want to call them? Give me a name, give me a name."

"Proud Boys, stand down and stand by, but I tell you what. Somebody has got to do something about antifa and the left because this is not a right-wing problem. This is a left-wing problem," Trump added.

"Antifa is an idea, not an organization," Biden said, quoting Trump's FBI director.

On the topic of race in America, Biden said he believes there is a systemic injustice in the U.S. on education, work and law enforcement, before offering praise to the majority of police officers.

"Look, the vast majority of police officers are good, decent, honorable men and women. They risk their lives every day to take care of us. But there are some bad apples and when they occur -- when they find them -- hey have to be sorted out. They have to be held accountable," Biden said. 

"It's a little bit like how this guy and his friends look down on so many people. They look down their nose on people like Irish Catholics like me, who grew up in Scranton. They look down on people who don't have money. They look down on people who are of a different faith. They look down on people who are a different color. In fact, we're all Americans," he continued. 

When confronted by Wallace about the rise in violence this summer in cities across the country -- run by both Democrats and Republicans -- Trump continued to blame the Democrats.

"I think it's a party issue," Trump said, even though Wallace brought up Tulsa, Oklahoma, and Fort Worth, Texas, both Republican-run cities.

Biden finished by urging Americans that the only way we can move forward is by coming together.

"The only way we're going to bring this country together is bring everybody together," Biden said.

"We can take this on and we can defeat racism," Biden added.
