Elections officials and voting experts say President Donald Trump gave bad advice when he encouraged mail-in voters to show up at polling places on Election Day and cast an in-person ballot if poll workers can’t confirm that their mail-in ballot was received.

In an interview with Fox News’ Laura Ingraham that aired over two days, President Donald Trump made several false, misleading and unsubstantiated claims.

Democratic presidential nominee Joe Biden claimed President Trump’s effort in court to nullify the Affordable Care Act would “take 100 million people with preexisting conditions and move them in a direction where they can’t get coverage.” They wouldn’t all lose coverage, as the claim suggests, barring highly unlikely circumstances.

The CDC hasn’t drastically reduced the number of deaths attributable to COVID-19, but that bogus claim has been circulating widely — boosted by President Trump.

President Trump retweeted a video, which had been posted under the misleading heading “Black Lives Matter/Antifa,” of a Black man shoving a white woman into a stopped subway car. The incident occurred on Oct. 23, 2019, and there is no indication that the man in the video was affiliated with either Black Lives Matter or antifa.

Republican ads aimed at Facebook users in Montana make the unsubstantiated claim that Gov. Steve Bullock “steered 14.3 million Montana dollars to his brother’s company.”

Contrary to QAnon-fueled claims that a California bill would legalize pedophilia, the bill would actually standardize the rules about who is required to be on the state’s sex offender registry.

Jill Biden hasn’t said that all Americans will be “required” to learn Spanish if her husband wins the 2020 presidential election, contrary to a false claim shared on social media. The quote first appeared in a headline from a website that calls its work satire.

Facebook posts falsely suggest that envelopes used for mail-in ballots in general elections reveal party affiliation, saying postal workers may “toss” votes. Voting experts say they don’t know of any such labels in general elections — only on envelopes during primary elections.

Q: Does a video shared on social media show Joe Biden sleeping during a live television interview?

A: No. The video was manipulated to make it appear that he had fallen asleep.
