TRUMP'S CLAIM: Trump said that "the mortality rate is down 85%" for COVID-19 in the United States, and that "the excess mortality rate is way down, and much lower than almost any other country."

FACT CHECK: Although Trump was correct to assert that death rates have fallen significantly since the spring, they are not down by 85%, but rather 62% -- and they are currently trending up again nationwide.

According to public health experts, much of that decline can be attributed to greater testing, better treatment protocols and to a larger number of younger people -- rather than older people -- becoming infected with COVID-19.

Meanwhile, "excess mortality" is an estimate of how many more people are dying than during a normal year, or other time period. It is incorrect to refer to the rate as "way down," since it is estimated that in the United States, there have been many more excess deaths compared to last year.

The Centers for Disease Control and Prevention reported on Tuesday 299,028 more people had died in the United States from late January to early October than would be expected in a typical year. It attributed 66% of those excess deaths, or 198,081, to COVID-19.

According to a report published in the Journal of the American Medical Association, "The US has experienced more deaths from coronavirus disease 2019 (COVID-19) than any other country and has one of the highest cumulative per capita death rates."

Analyzing the number of deaths per 100,000 people attributed to the pandemic, the U.S. had 60.3 deaths per 100,000 people. That was higher than Germany (11.3), Canada (24.6) and France (46.6), but lower than Belgium (86.8) and the United Kingdom (62.6), according to the report.

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.

Debate organizers removed the plexiglass barriers initially placed between the candidates’ lecterns after speaking with the government’s top expert on infectious diseases Dr. Anthony Fauci.

Fauci told ABC News Chief White House Correspondent Jonathan Karl that he got a call from Trump’s chief of staff Mark Meadows asking if in his opinion there was a need to have plexiglass between the two candidates.

Meadows then had Fauci talk to a doctor working with the Commission on Presidential Debates, and Fauci explained to the doctor that because the candidates were 12-feet apart, there was no need for plexiglass as droplets wouldn’t reach that far and aerosol isn’t stopped by plexiglass anyway.

Even with the removal of the plexiglass partitions, the coronavirus pandemic is still on display inside the debate hall at Belmont University in Nashville.

All audience members are required to wear masks and will be removed from the event if they refuse, organizers said. The mask requirement comes after several members of the Trump family removed their masks once seated at the first presidential debate in Cleveland.

Singer Kid Rock and professional golfer John Daly, both Trump supporters, were spotted in the audience ahead of the debate’s start without their masks. They put them back on after they were approached by debates staffers.
