Hunter Biden has reached a deal with federal prosecutors to resolve a five-year federal investigation into his failure to pay about $1 million in federal taxes and his purchase of a handgun in 2018.

Under an agreement detailed Tuesday in a filing in federal court in Delaware, President Joe Biden’s son will plead guilty to a pair of misdemeanor tax charges. Prosecutors have also charged him with possessing a firearm while being a user of illegal drugs — a felony — but have agreed to dismiss that charge if he completes a two-year period of probation.

Hunter Biden, 53, is unlikely to serve time in prison if he complies with release conditions. The deal calls for both sides to recommend that he be put on probation.

The probe was overseen by Delaware U.S. Attorney David Weiss, who was appointed by former President Donald Trump and was permitted to stay in his post after Joe Biden took office in order to complete the investigation of the president’s son. The White House and the Justice Department have said they did not interfere with Weiss’ investigation.
