President Joe Biden's son Hunter Biden has reached a deal on federal charges related to tax crimes and the illegal purchase of a handgun while he was an illicit drug user, the Justice Department wrote in a court filing Tuesday.

The president's son has agreed to plead guilty to two counts of "willful failure to pay" his federal income taxes, and the Justice Department said Hunter Biden will be entering a "Pretrial Diversion Agreement" pertaining to possession of a firearm "by a person who is an unlawful user of or addicted to a controlled substance," according to the filing.

This is a developing story and will be updated.
