The White House announced Trump will vote early in Florida on Saturday.

"President Trump plans to early vote on Saturday in West Palm Beach, Florida," spokesman Judd Deere said.

It had been expected that the president would vote absentee, because even as he has railed against mail-in voting, he has also justified his own practice of voting absentee in the past.

With early voting having kicked off in all 50 states plus Washington, D.C., at least 47 million votes have already been cast in the 2020 general election as early voting data continues to break records across the country.

In 2016, there was a total of 47 million early votes cast, meaning the country has narrowly passed its 2016 early voting data with 12 days still left.

According to the United States Elections Project, spearheaded by University of Florida's political expert Michael McDonald, as of Thursday at 5 p.m. ET an unprecedented 47,095,528 voters have already cast their ballots and at least 85,133,505 ballots have been requested in early voting states.

TargetSmart, a Democratic firm that collects political data including early voting statistics, reports that 10 million voters who have already voted in the 2020 election did not participate in the 2016 election. Many of these early votes are coming from young voters as well as first time voters with individuals under 30 years old having cast 9.1% of early votes.

During an earlier press conference, TargetSmart predicted that there will still be an additional 40 million early votes as well as between 60-70 million votes on Election Day. Their prediction allots for at least 150 million ballots cast. In comparison, in the 2016 election, there were 138 million total votes.

Plexiglas partitions were placed on the debate stage next to each candidates' lectern -- already set up at least 12 feet apart -- as a coronavirus precaution for the second and final presidential debate in Nashville.

According to a source familiar with the debates, the partitions were added under the direction of the Cleveland Clinic as part of its responsibility to keep debate participants safe.

Plexiglass became an issue prior to the vice-presidential debate when the two campaigns squabbled over whether to have physical barriers separate the two candidates.

The insistence on barriers was initially met with resistance by Vice President Mike Pence's team, but they were ultimately used.

TRUMP'S CLAIM: "Nobody knew where it was coming from, what it was. We've learned a lot. But Anthony said don't wear masks. Now he wants to wear masks."

FACT CHECK: Dr. Anthony Fauci, one of the top infectious disease experts in the country, and other public health experts initially told Americans not to wear surgical or N95 masks in the early days of what has become the COVID-19 pandemic.

At the beginning of the pandemic, the Centers for Disease Control and Prevention and the World Health Organization, as well as Fauci and other top experts, initially discouraged wearing masks because of concerns that masks and other personal protective equipment were in short supply for health care workers who needed them. Public health officials were also concerned wearing masks could have unintended consequences if people touched their face more often to adjust them or fail to keep social distancing.

"There was this feeling that there would be a shortage just for those who really need them very early on," Fauci said in a recent interview. "That was the big deal. We didn't have enough PPE including masks. Then it became clear that cloth masks worked reasonably well. And therefore there was no more shortage. Then the different analyses, meta analyses and others came in that in fact, it does work."

In early April, the CDC changed its recommendation about face coverings for the general public, based on evidence that a significant number of people who were asymptomatic or not yet feeling sick were transmitting the virus.

Duke University researchers have also concluded that "if 95 percent of people wear cloth masks when within 6 feet of other people in public, it will reduce COVID-19 transmission by at least 30 percent."

Trump also said he thought Fauci was a Democrat, but Fauci is not registered as a member of any political party, according to D.C. voting records.
