On Thursday, he started floating a new birther lie about Sen. Kamala Harris, who, if elected, would be the first Black and Asian American vice president. Trump's incendiary nonsense about Harris was part of a Thursday self-described "news conference" he largely used to campaign against his Democratic election opponents. Trump also made a series of false claims about former Vice President Joe Biden, Democrats more broadly, and, again, about mail-in voting. Kamala Harris's eligibility Trump was told about claims on "social media" that Harris might be ineligible to serve as president and vice president. He was then asked if he can definitively say that she meets the requirements. Trump said, "I heard today that she doesn't meet the requirements." He referred to a lawyer who raised the issue in a Newsweek article, Chapman University professor John Eastman, as "very highly qualified." Trump then said he has "no idea" whether it's true Harris doesn't meet the requirements. He then asked the reporter if she was saying Harris doesn't qualify because Harris "wasn't born in this country." Facts First: Harris was born in Oakland, California. Therefore, as a natural born citizen, she meets the Constitution's requirements to serve as vice president or president. There is no serious question about this. The fact that Harris's parents were immigrants -- her father came from Jamaica, her mother from India -- does not change the fact that she is indisputably eligible. Trump did say that is not certain if Harris is eligible or not; he concluded his comments by saying, "I just heard about it, I'll take a look." Nonetheless, his just-asking-questions posture -- which he also employed with his Obama birtherism -- doesn't change the fact that he gave credence to the conspiracy theory by praising the author of the article, saying he had heard Harris is not eligible, and raising the possibility that Harris was not born in the US. Trump spent the beginning of his news conference lambasting Biden. Here's a look at the facts around some of those attacks. Biden and pandemic plans Trump claimed that he has already done everything Biden has called on him to do in responding to the pandemic. "In fact, many of the things -- it was well reported over the last few days -- every single thing he said to do, every single thing, we did, and we did 'em well." Facts First: It's not true that Trump has done every single thing Biden has called for. While there is certainly some overlap in Biden's proposals and Trump's actions, Biden has made a number of proposals Trump has not implemented. For example, Biden has called on Trump to "form a Public Health Jobs Corps -- hiring at least 100,000 Americans to help build a data-driven disease surveillance system to spot and stem flare-ups before they spread." Trump has not done this. Biden has also called on Trump to provide complete information on the state of testing around the country, "including the number of tests com
