Twitter fact-checks Biden's claim on billionaire taxes.

President Joe Biden's Twitter account posted a graphic with a dubious statistic claiming that American billionaires pay an average tax rate of 3%. However, it is unclear where the figure came from, and it contradicts figures the White House has issued in the past. Twitter CEO Elon Musk disputed the claim, stating that he paid 53% taxes on his Tesla stock options and more income tax than anyone ever in the history of Earth for 2021 and will do that again in 2022.
