1st presidential debate between Trump and Biden spirals into chaotic clash

TRUMP'S CLAIM: “He's talking about defunding the police.”

FACT CHECK: From the debate stage during an exchange on law enforcement, Trump implied that Biden wants to defund the police. Biden has said repeatedly that he doesn’t want to “defund the police.” 

"No, I don't support defunding the police," he said in a June interview with CBS News, adding he supports conditions on federal aid based on meeting "basic standards of decency."

Biden has in the past claimed that Trump has proposed cutting police funding by “half a billion dollars.” 

The former vice president is referencing a proposed $465.8 million cut to community police efforts through the Office of Justice Programs, which could lose funding under Trump’s proposed 2021 budget, like the COPS Hiring program, which offers grants to local law enforcement agencies to hire officers. 

Biden has been at odds with many activists for his role as chairman of the Senate Judiciary Committee co-writing and pushing the 1994 Crime Bill. Biden has defended his role in the bill’s passage and has supported putting more police officers on the streets in communities. After the killing of George Floyd, Biden has called for reforms like buying body cameras, de-escalation training for officers and adopting a national use-of-force standard.

TRUMP'S CLAIM: Can you imagine where they say you have to have your ballot in by Nov. 10? Nov. 10. That means that's seven days after the election, in theory, should have been announced. We have major states with that -- all run by Democrats, all run by Democrats. It's a fraud. It's a rigged election. 

FACT CHECK: It is true that mail ballots arriving after Nov. 3 will be counted in several states, but these ballots are not fraudulent.

For these mail ballots to be counted, they must be postmarked on or before Election Day, and in some states, they must be postmarked by the day before the election.

In a normal election year, 19 states accept ballots that arrive after the election, as long as they are properly postmarked and arrive within a state-specific timeline, between three and 14 days post-election, according to the National Conference of State Legislatures. These states are not "all run by Democrats" either. Alaska, Iowa, Maryland, Mississippi and Ohio -- all states with Republican governors currently -- have postmark-by deadlines on the books, even when there isn't a pandemic causing widespread changes to voting. 

More states will have postmark-by deadlines for the November election, due to both court rulings and changes implemented by state officials. 

In Wisconsin on Tuesday, for example, a federal appeals court upheld a lower court's ruling, which ordered county election officials to accept ballots received up to six days post-election as long as those ballots were postmarked on or before Nov. 3. Other battleground states where court rulings have extended the deadline for mail ballots to arrive include Michigan, Pennsylvania and Georgia, but the extension is being challenged in all three states. 

In Kentucky, Democratic Gov. Andy Beshear and Republican Secretary of State Michael Adams reached a bipartisan agreement in mid-August to accept ballots returned by mail through Nov. 6, as long as those ballots are postmarked on or before Nov. 3.

Following the debate, Biden campaign officials said they had their best fundraising hour of the entire campaign between 10 p.m. and 11 p.m. ET and that the former vice president’s callout during the debate to Iwillvote.com led to the most concurrent users in the website’s history. 

TRUMP'S CLAIM: "It's China's fault, it should have never happened. They stopped it from going in. But it was China's fault. By my doing it early -- in fact, Dr. Fauci said, 'President Trump saved thousands of lives.' Many of your Democrat governors said, 'President Trump did a phenomenal job.'"

FACT CHECK: Trump is overstating his early actions in containing the virus by suggesting his travel restrictions from China were critical. 

While Dr. Anthony Fauci has confirmed that those restrictions were important, Trump is omitting a major miscalculation he made early on in the pandemic -- not restricting travel from Europe. 

"The president's decision to essentially have a major blocking of travel from China, that already had an effect of not seeding the way, in Europe," Fauci told ABC News Chief Anchor George Stephanopoulos on "This Week" in March. "What we're doing now with the other travel restrictions -- so you block infections from coming in," Fauci continued, adding that containment and mitigation efforts were implemented to keep us away from that worst-case scenario."

Up to 75% of the coronavirus specimens circulating in the New York City area in early March were genetically similar to strains seen in Europe and other areas of North America, according to a Centers for Disease Control and Prevention study published in July.

Although Fauci has said that the president's travel restrictions did save lives, he has also stated on numerous occasions that if mitigation efforts such as social distancing and mask wearing were implemented earlier, then many lives could have been saved.

"I mean, obviously, you could logically say that if you had a process that was ongoing and you started mitigation earlier, you could have saved lives. ... If we had right from the very beginning shut everything down, it may have been a little bit different," Fauci said during an interview on CNN in April.
