The Supreme Court heard oral arguments in the latest legal challenge to the constitutionality of the Affordable Care Act today. There are a range of possible outcomes in the case.

Experts — and the federal Cybersecurity and Infrastructure Security Agency — have said the theory is a hoax and that safeguards, including paper trails, would deter such an effort.

Campaign officials for President Donald Trump and supporters have promoted the faulty claim that Joe Biden received nearly 100,000 votes in Georgia through ballots that only included selections for president, suggesting it’s “suspicious.” But the claim ignores that some voters do not vote a straight-party ballot.

A misleading claim that more than 21,000 registered voters in Pennsylvania are dead is circulating online. The figure comes from a conservative group that failed to convince a federal judge in October that its list was accurate.

Viral social media posts claim that the website RealClearPolitics rescinded a projection that Joe Biden had won Pennsylvania. But the website never called the state in the first place; many other media outlets have made that call.

President Donald Trump’s campaign pushed an altered image of a Washington Times front page to cast doubt on the 2020 election calls made by news outlets. The newspaper never ran the purported front page, declaring Al Gore the winner of the 2000 election.
