Biden was charged with nine tax-related counts Thursday, adding to three federal gun charges he’s already pleaded not guilty to.

The prosecutors say President Biden’s son lied on his taxes in 2020, well after he had kicked the drug habit he has long cited as a mitigating factor for his wrongdoing.

Federal criminal tax evasion charges like those filed against Hunter Biden this week are "very rare", experts say. Prosecutors allege the president's son evaded $1.4m (£1.1m) in taxes between 2016 and 2019 and used his income to fund an "extravagant lifestyle" that included drugs and escorts.
