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 light of President Trump's positive COVID-19 diagnosis and subsequent concerns from Harris' team, the Commission on Presidential Debates agreed to add additional safety precautions to Wednesday's debate at the University of Utah.

Unlike last week's presidential debate, everyone in the audience will be required to wear a face mask or covering and those who don't will be escorted out of the venue.

"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," Frank Fahrenkopf, chairman of the Commission on Presidential Debates, told ABC News.

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

And the candidates will be separated by more than just the issues -- or at least one of them will be.

After Pence's close proximity to others who have tested positive for COVID-19, the Harris campaign requested plexiglass barriers be used at the debate and the commission agreed -- but the Pence campaign said Tuesday that they never agreed to a plexiglass partition.

A senior administration official in Pence's office told ABC News Tuesday that the CPD decided to publicize the new safety protocols before any formal agreement was made and that the moderator and the Harris campaign can do as they want, "but we do not."

The official said Center for Disease Control and Prevention guidelines recommend plexiglass whenever 6 feet of separation isn't possible, but noted the candidates will be 12-feet apart on stage. The comment fell in line with Pence's chief of staff Marc Short who told The Washington Post Tuesday that plexiglass is "not needed."

Pence's communications director, Katie Miller, who tested positive for COVID-19 in May, also responded to the request in a statement to Axios earlier this week saying, "If Sen. Harris wants to use a fortress around herself, have at it."

Following news that Miller's husband, senior Trump aide Stephen Miller, tested positive for the coronavirus, she reportedly left Utah and a spokesperson declined to comment if Pence would agree to plexiglass.
