Son of U.S. President Joe Biden, Hunter Biden, is facing a series of criminal charges in connection with a prolonged investigation by the Justice Department into his taxes.

This marks the second criminal case initiated by special counsel David Weiss against President Biden’s son.

The charges, comprising nine counts, include three felony and six misdemeanor tax offenses, as revealed in an indictment filed in U.S. District Court in Central California.

If convicted on these charges, Hunter Biden could be sentenced to up to 17 years in prison. The Justice Department has confirmed that the investigation into Biden is ongoing.

According to the indictment, “The Defendant engaged in a four-year scheme to not pay at least $1.4 million in self-assessed federal taxes he owed for tax years 2016 through 2019.” It further alleges that instead of settling his tax bills, Hunter Biden “spent millions of dollars on an extravagant lifestyle.”

The charges highlight Hunter Biden’s substantial earnings while serving on the boards of a Ukrainian industrial conglomerate and a Chinese private equity fund.

As his income increased, so did his expenditures, with the indictment stating that in 2018 alone, he “spent more than $1.8 million, including approximately $772,000 in cash withdrawals, approximately $383,000 in payments to women, approximately $151,000 in clothing and accessories,” among other costs.

“The Defendant did not use any of these funds to pay his taxes in 2018,” the indictment added.

A spokesperson for Weiss and Hunter’s lawyer have not yet responded to requests for comments.

This development follows Hunter Biden’s previous plea of not guilty in October to charges in Delaware related to alleged false statements about his drug use during the purchase of a handgun.

This marked the first criminal prosecution of a sitting U.S. president’s child.

Weiss overseeing the investigation into Hunter, has utilized a grand jury in Los Angeles to gather documents and seek testimony from multiple witnesses as part of the federal inquiry into his business dealings, as reported by CNN last month.
