He has since paid his back taxes, so this isn't a valid argument.
"In the year after he disclosed a federal investigation into his “tax affairs” in late 2020, President Biden’s son, Hunter Biden, paid off a significant tax liability, even as a grand jury continued to gather evidence in a wide-ranging examination of his international business dealings, according to people familiar with the case.
Mr. Biden’s failure to pay all his taxes has been a focus of the ongoing Justice Department investigation. While wiping out his liability does not preclude criminal charges against him, the payment could make it harder for prosecutors to win a conviction or a long sentence for tax-related offenses, according to tax law experts, since juries and judges tend to be more sympathetic to defendants who have paid their bills."
The rich evading taxes is theft. Unfortunately you'll probably see where these pathetic evasions end up in November... a complete inability to respond to these ridiculous issues the Repubicans are attracting people with, it's like 2016 all over again. Good luck with winning the online debate wars while you lose everything else. After WW2 all the citizens of Germany shared blame, so it will be for Americans.
