WILMINGTON, Del. (AP) — President Joe Biden’s son Hunter is expected to appear before a federal judge on Wednesday to plead guilty to two tax crimes and admit possessing a gun as a drug user in a deal with the Justice Department that's likely to spare him time behind bars.

U.S. District Court Judge Maryellen Noreika, who was appointed by then-President Donald Trump, will preside over the hearing and must sign off on the deal, in which prosecutors are recommending two years of probation. Hunter Biden is not expected to be sentenced on Wednesday.

The deal, announced last month, comes after a yearslong Justice Department investigation into the taxes and foreign business dealings of the Democratic president's second son, who has acknowledged struggling with addiction following the 2015 death of his brother, Beau Biden.

While legally this will clear the air for Hunter Biden and avert a trial that would have generated weeks or months of distracting headlines, the politics remain as messy as ever, with Republicans insisting he got a sweetheart deal and the Justice Department pressing ahead on investigations into Trump, the GOP's 2024 presidential primary front-runner.

Trump is already facing a state criminal case in New York and a federal indictment in Florida. But last week, a target letter was sent to Trump from special counsel Jack Smith that suggests the former president may soon be indicted on new federal charges, this time involving his struggle to cling to power after his 2020 election loss to Joe Biden.

Republicans claim a double standard, in which the president's son got off easy while the president's rival has been unfairly castigated. Congressional Republicans are pursuing their own investigations into nearly every facet of Hunter Biden's dealings, including foreign payments.

On Tuesday, a dustup arose after Republicans on the House Ways and Means Committee filed court documents urging Noreika to consider testimony from IRS whistleblowers who alleged Justice Department interference in the investigation.

Shortly after their motion was filed, a court clerk received a call requesting that “sensitive grand jury, taxpayer and Social Security information” be kept under seal, according to an oral order from the judge. The clerk said the lawyer gave her name and said she worked with an attorney from the Ways and Means Committee but was in fact a lawyer with the defense team.

Noreika demanded the defense team show why she should not consider sanctioning them for “misrepresentations to the court.” Defense attorneys responded that their lawyer had represented herself truthfully from the start and called the matter a misunderstanding.

President Biden, meanwhile, has said very little publicly, except to note, "I'm very proud of my son."

Under the terms announced last month, Hunter Biden will plead guilty to two misdemeanor tax charges of failure to pay more than $100,000 in taxes from over $1.5 million in income in both 2017 and 2018. The back taxes have since been paid, according to a person familiar with the investigation who spoke to The Associated Press on the condition of anonymity. The maximum penalty for the charges would be a year in prison.

Hunter Biden also was charged with possession of a firearm by a person who is a known drug user: He had a Colt Cobra .38 Special for 11 days in October 2018. According to the pre-trial agreement, he agreed to enter into a diversion agreement, which means that he won't technically plead guilty to the crime, but if he adheres to the terms of his agreement the case will be wiped from his record. If not, the deal is withdrawn. This type of agreement is an option usually for nonviolent offenders with substance abuse issues. Otherwise, the charge carries a maximum sentence of 10 years in prison.

Christopher Clark, a lawyer for Hunter Biden, said in a statement last month when the deal was announced that it was his understanding that the five-year investigation had now been resolved.

“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,” Clark said then. “He looks forward to continuing his recovery and moving forward.”
