PENCE'S CLAIM: Pence said that Trump's decision to impose travel restrictions from China, ultimately "bought" the U.S. "invaluable time" to save hundreds of thousands of American lives, reinvent testing capacity and deliver billions of supplies to doctors and nurses.

FACT CHECK: Although the U.S. has conducted more COVID-19 tests than any other country, according to experts, testing capacity is still not vast or fast enough to serve all the people who need to get a test.

Additionally, although billions of items of personal protective equipment, or PPE, have been delivered to frontline workers across the country, the United States continues to experience shortages of PPE and testing supplies, according to a Sept. 21 report from the U.S. Government Accountability Office.

In April, Trump said that the U.S. would be conducting up to 5 million tests per day, "very soon." However, the national 7-day average of coronavirus tests has yet to surpass 1 million, according to the COVID Tracking Project.

To date, the U.S. has conducted over 120 million COVID-19 tests, according to the Centers for Disease Control and Prevention. 
More testing will, of course, identify more cases.

However, according to data compiled by Johns Hopkins University, there are several countries that have conducted more testing per capita than the U.S., but also have fewer cases per capita than the U.S. does -- such as the U.K., Spain and the United Arab Emirates. Those figures reflect all-time averages of daily tests conducted per capita -- and the daily percentage of tests that come back positive, which is known as the "positivity rate" or the "percent positive rate."

Despite having one of the highest rates of tests per capita, the U.S. faces the largest outbreak in the world and new cases continue to trend upward in many states. The percent positivity in the U.S. remains over 4.7%, when other countries with high testing figures report a significantly lower percent positivity rate, according to Johns Hopkins.

Meanwhile, the shortages of PPE and testing supplies are due to high global demand and the fact the domestic production of supplies is limited. According to the Government Accountability Office, "testing supply shortages have contributed to delays in turnaround times for testing results.

"Delays in processing test results have multiple serious consequences, including delays in isolating those who test positive and tracing their contacts in a timely manner, which can in turn exacerbate outbreaks by allowing the virus to spread undetected," the report read.

Shortly after the debate wrapped, Trump -- known to enjoy his time in front of the television -- signaled his approval of Pence's performance and declared him the winner in a tweet.

The Trump campaign also released a statement in which Pence's chief of staff Marc Short said the vice president made the argument to the American people that Trump is "the clear choice to rebuild the economy."

Social media users clamored to point out that Pence's eye looked red and enflamed, which led to speculation about his health after being exposed to COVID-19 from the president.

ABC News' Chief Medical Correspondent Dr. Jennifer Ashton weighed in, saying that pink eye has been reported in anywhere from 11% to 30% of COVID-19 cases. But as always, Ashton said that it is not possible to diagnose anyone from television and that it was a possibility that it could just be that he just had "some makeup in his eye."

An errant fly that landed on Pence's head during the debate also grabbed the attention of social media users. The Biden campaign immediately seized on the moment, using it as an opportunity to fundraise, posting a tweet asking for donations to "help this campaign fly," along with a photo of Biden holding a fly swatter.

Sen. Harris was once a proponent of the Green New Deal as both a co-sponsor of Sen. Bernie Sanders' bill and as a presidential candidate.

Since becoming Biden's running mate, Harris has moved away from her support, instead, embracing Biden's climate plan, which calls for the U.S. to rejoin the Paris Climate agreement, aims for the U.S. to get to net-zero carbon emissions by 2050 and invests $2 trillion in clean energy and infrastructure.

Fracking contributes to the economy in Pence's home state of Indiana and he's an advocate for the fossil fuel industry. He once called global warming a "myth," but has evolved slightly to say "there's no question" human activity has "some impact on climate change." He touts the economic sectors of oil, gas, fracking and coal as areas that boost job creation and the overall economy. He also hailed Trump for removing the U.S. from the Paris Climate Agreement, which he has called a "bad deal since the moment it was signed" by the Obama administration in 2015.

He also misleadingly told a group of farmers and ranchers in Iowa that he was not going to let Harris reduce the amount of red meat Americans should eat, referencing a comment she made during a 2019 CNN town hall as a way to curb the impact of climate change.

"Sen. Kamala Harris said she would change the dietary guidelines of this country to reduce the amount of red meat Americans can eat. Well, I've got some red meat for you. We're not gonna let Joe Biden and Kamala Harris cut America's meat."

Changing health guidelines does not necessarily mean Americans will be required to implement them, they are only recommendations.

During the 2019 town hall, Harris was asked if she "would support changing the dietary guidelines" in the U.S. to reduce red meat consumption and she answered, "yes." She said, "I love cheeseburgers from time to time," but that there needs to be more education surrounding "the effect of our eating habits on our environment."
