TRUMP'S CLAIM: "So as you know, 2.2 million people modelled out were expected to die."

FACT CHECK: It is true that, in the spring, one early model predicted more than 2 million deaths from the COVID-19 pandemic, although the model said the death toll would only be that high no attempts were made to control the pandemic.

During a March 29 White House coronavirus task force press briefing, Trump and White House coronavirus response coordinator Dr. Deborah Birx said that models showed up to 2.2 million people could die from COVID-19 in the United States "if we did nothing," as the president put it.

This was an estimate of potential deaths if neither the government, nor individuals, choose to alter their behavior, despite the pandemic.

The prediction may have been drawn from a model by Neil Ferguson, an epidemiology professor at Imperial College London, which found that an "unmitigated epidemic," could result in "2.2 million (deaths) in the US."

TRUMP'S CLAIM: "We are energy independent for the first time."

FACT CHECK: The U.S. exports more energy products like oil and liquid natural gas than it exports, but many parts of the country still rely on oil from other countries.

But the U.S. is not fully energy independent.

The amount of oil produced in the U.S. is about 1.25 million barrels a day short of demand, according to the U.S. Energy Information Administration, and while imports are at a record low the country still relies on imported products for 3% of domestic petroleum consumption.

One of Trump's goals has been to make the U.S. energy independent, in part by expanding oil and gas drilling around the country including on public lands.

Last year, U.S. energy exports surpassed imports for the first time since 1952, largely due to increases in natural gas production.

TRUMP'S CLAIM: "He's been in government 47 years. He never did a thing, except in 1994, when he did such harm to the Black community. And they were called, and he called them 'super predators.' And he said that. He said it, 'super predators.' And they have never lived that down."

FACT CHECK: It was then-first lady Hillary Clinton who used the phrase "super predators" in 1996, while expressing her support for the 1994 crime bill.

Both former Biden and Trump have made past references to Americans being "predators."

In a speech from on the floor of the Senate in 1993, Biden said, "We have predators on our streets that society has in fact, in part because of its neglect, created." He added, "They are beyond the pale many of those people, beyond the pale, and it's a sad commentary on society. We have no choice but to take them out of society."

Trump, in his 2000 book "The America We Deserve," wrote several times about "predators."

"The perpetrator is never a victim," Trump wrote. "He's nothing more than a predator, and there can be no excuses made for killing old ladies, beating old men, or shooting adolescents."

Trump added: "If I were in charge of things, life would be even tougher for these predators. If there was a situation in New York like that terrible dragging death in Texas, I'd not only put the perpetrators to death, I'd find some way to make them an example to others."

The final topic of the night was climate change with Welker first asking each candidate how he would combat climate change and support job growth at the same time as president. Trump answered first.

"So we have the trillion trees program. We have so many different programs. I do love the environment, but what I want is the cleanest, crystal clear water, the cleanest air," Trump said, taking credit for the country's reduced carbon emission last year.

He went on to slam other counties air-quality and tout the U.S. by comparison.

"Look at China, how filthy it is. Look at Russia. Look at India. It's filthy. The air is filthy. The Paris Accord, I took us out because we were going to have to spend trillions of dollars, and we were treated very unfairly," Trump said, closing his two minutes by saying his administration has done an incredible job "environmentally."

When it was Biden's turn, he pivoted to the existential threat he says global warming poses to humanity and said the U.S. has a moral obligation to "deal with it" -- but said climate change also creates a prime opportunity for new jobs.

"Here's where we have a great opportunity. I was able to get both all the environmental organizations as well as labor, the people worried about jobs, to support my climate plan. Because what it does -- it will create millions of new good-paying jobs," Biden said. "Wall Street firms indicated that my plan -- my plan will, in fact, create 18.6 million jobs, 7 million more than his. This is from Wall Street. And I'll create $1 trillion more in economic growth than his proposal does. Not on climate, just on the economy."

Trump slammed Biden's response, claiming the former vice president's plan would cause a massive economic depression and deeming it a "pipe dream," before raising Biden's stance on fracking.

In the face of Trump's criticisms, Welker asked Biden directly, "Would you rule out banning fracking?"

"I do rule out banning fracking," Biden said. "We need other industries to transition to get to ultimately a complete zero emissions by 2025. What I will do with fracking over time is make sure we can capture the emissions from the fracking, capture the emissions from gas. We can do that and we can do that by investing money. It's a transition to that."

"Excuse me," Trump interrupted. "He was against fracking. He said it. I will show that to you tomorrow."

"Fracking on federal land, I said," Biden responded. "No fracking and/or oil on federal land."
