President Joe Biden s son Hunter pleaded not guilty for now on two tax charges Wednesday, after an earlier plea deal fell apart when a judge scrutinized a related agreement regarding a more significant gun possession charge.

Earlier on Wednesday, U.S. District Court Judge Maryellen Noreika refused to sign off on a previous agreement that Hunter Biden made with prosecutors, in which hed plead guilty to two misdemeanor charges for failure to pay taxes, and would enter a diversion program in place of pleading guilty to felony gun possession as an admitted drug user.

As discussed in court Wednesday, Biden will reverse his not guilty plea if his lawyers and prosecutors can agree in the next few weeks on a plea deal that satisfies Noreika. She has asked each side to submit additional briefs detailing the legal structure of the potential new agreement.

As part of the previous agreement , prosecutors planned to recommend two years of probation for Bidens failure to pay taxes on more than $3 million he earned between 2017 and 2018. The diversion program required Biden to remain drug-free for two years and not commit any additional crimes in exchange for dismissal of the gun charge, which concerned his possession of a Colt Cobra .38 Special for 11 days in October 2018.
