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.

In response to COVID-19 concerns from Kamala Harris’ team, the Commission on Presidential debates has agreed to add additional safety precautions at the debate.

Vice President Mike Pence and Harris will be seated 12-feet and 3-inches away from each other and from the debate moderator, USA Today Washington Bureau Chief Susan Page. As was the case at the presidential debate, there will be no handshakes between the candidates, and while the Commission said there would also be plexiglass separating Harris, Pence and Page, the Pence campaign has objected to using it.

A senior administration official in Pence’s office told ABC News Tuesday that there had been no formal agreement about the plexiglass and that while Harris and Page could use it, Pence doesn’t want to.

In a statement to ABC News, Pence spokeswoman Katie Miller said, "If Sen. Harris wants to use a fortress around herself, have at it."

Though Harris, Pence and Page will not wear masks on stage, everyone else in the debate hall will be required to wear one. Anyone who takes their mask off will be escorted out, according to the rules.

During the presidential debate in Cleveland, members of the Trump family were seen sitting in the audience without masks, even after being asked to put them on.

Harris and Pence will be tested prior to the debate, according to the Commission, which is a change from the presidential debate when the campaigns were responsible for testing their candidates and traveling parties.

“They’ve got to wear a mask, and if they take their mask off they're gonna be escorted out, and I don't care who they are, they'll be escorted out,” said Frank Fahrenkopf, chairman of the Commission on Presidential Debates, in an interview with ABC News.

The vice president has tested negative each day since Friday, and his White House physician has cleared him from having to quarantine, citing that he is not a “close contact” with anyone who’s tested positive, including Trump.

But Pence was present at the Rose Garden ceremony on Sept. 26 when Trump announced Judge Amy Coney Barrett as his U.S. Supreme Court nominee. Eleven of the attendees have since tested positive for COVID-19. He was also in the Oval Office with Trump the morning of his debate, just days before the president tested positive.

Harris tested negative for COVID-19 Monday after being screened in Salt Lake City, where she has been gearing up for the debate, according to an aide.
