Hunter Biden, the son of President Joe Biden, could soon be facing criminal charges related to tax evasion and falsifying information on a gun background check form. Federal prosecutors are currently considering bringing charges against him, according to NBC News.

The charges would include two misdemeanor counts of failing to file taxes, one felony count of tax evasion, and one felony count for the gun-related charge.

Sources within the FBI and the Internal Revenue Service (IRS) have expressed frustration over the slow pace of the investigation. It was reported that investigators completed most of their work on the case a year ago, and the IRS concluded its investigation over a year ago. Nevertheless, no charges have been filed.

NBC Reports:

The federal investigation of Hunter Biden began in 2018. It has narrowed from an inquiry into his international business relationships, including any possible national security implications, to an examination of the income he earned from those ventures and a false statement he’s alleged to have made during the gun purchase, the sources said.

In 2018, during a period when he has admitted using cocaine, Hunter Biden purchased a firearm, which required him to fill out a form that included a question about whether he was addicted to or abusing any unlawful substance.

The investigation into Hunter Biden’s business dealings began in 2018, and it has since focused on his income from those ventures and a false statement he allegedly made when purchasing a firearm. The purchase required him to disclose whether he was addicted to or abusing any unlawful substance, but he reportedly did not disclose his cocaine use.

On Thursday, a whistleblower from within the IRS claimed that the department covered up Hunter Biden’s alleged tax evasion. The allegations are the latest in a string of controversies surrounding the president’s son, who has faced criticism for his business dealings and personal life. The decision on whether to bring charges against Hunter Biden rests with US Attorney David Weiss.
