Hunter, the son of United States President, Joe Biden, is expected to plead guilty to two misdemeanour tax crimes and admit to illegally possessing a gun while a drug user, after a five-year investigation.

The U.S. Attorney in Delaware has filed papers indicating a plea agreement has been reached.

Hunter Biden, 53, is expected to agree to drug treatment and monitoring, while the terms of the agreement are likely to keep him out of jail.

The justice department, in a statement, said he still faces a maximum penalty of a year in prison on each of the tax charges and 10 years in prison on the gun charge.

The proposed deal would need to be approved by the judge in the case, who will also determine the sentence.

It is unclear when Hunter Biden will appear in court to enter his guilty plea on the tax charges.

He will admit to felony gun possession as part of a “pre-trial diversion agreement” that is separate to the plea deal, his lawyer, Chris Clark, said in a statement.

Clark added: “I know Hunter believes it is important to take responsibility for these mistakes he made during a period of turmoil and addiction in his life.

“He looks forward to continuing his recovery and moving forward.”

Hunter has previously worked as a lawyer, and a lobbyist including abroad in China and Ukraine.

He was discharged from the U.S. Navy in 2014 after testing positive for cocaine.

The plea deal brings to an end a long-running justice department investigation into whether he properly reported his income and made false statements on paperwork used to purchase a firearm in 2018.

According to BBC, the two misdemeanour tax charges stem from a failure to pay more than $100,000 in taxes in both 2017 and 2018.

The gun charge stems from a 2018 possession of a firearm while a drug user.

In a 2021 book, the younger Biden admitted to being a heavy user of crack cocaine at that time.

But he reportedly said “no” on a federal form asking if he was “an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug or any other controlled substance”.

The deal comes as some Republican lawmakers and presidential candidates have accused Joe Biden of “weaponising” the justice department against political opponents.

Hunter Biden has long been a target of scrutiny from conservatives, who have alleged that his dealings overseas indicate a pattern of corruption.

News of the plea deal was met with swift and strong criticism from Donald Trump and his campaign, as well as senior congressional Republicans.

A spokeswoman for the pro-Trump Make America Great Again Inc, Karoline Leavitt, called the agreement a “sweetheart deal” that allows the justice department to “turn a blind eye” to corruption.

Trump, for his part, called the deal a “mere traffic ticket”.

In a brief statement, the White House also said Joe Biden and First Lady Jill Biden “love their son and support him as he continues to rebuild his life. We will have no further comment”.

While the younger Biden has detailed a troubled life and “massive drug addiction”, he long denied engaging in illegal activity.

He first admitted knowledge of an investigation into him in December 2020.

In a statement at the time, he said he was “confident that a professional and objective review of these matters will demonstrate that I handled my affairs legally and appropriately, with the benefit of professional tax advisers”.

The justice department statement said the investigation is “ongoing”.
