WASHINGTON (NEWSnet/AP) — A legal showdown over the derailed plea deal for Hunter Biden continued Tuesday, as prosecutors asserted that an agreement regarding a gun charge is off the table.

The agreement was supposed to have wrapped investigation of President Joe Biden's son, but unraveled last month at a court hearing. Prosecutors said the two sides had continued to negotiate until the defense rejected a final counterproposal, the day before U.S. Attorney David Weiss asked to be named special counsel.

Lawyers for Hunter Biden have argued that prosecutors reneged on an arrangement on tax charges, but said a separate agreement sparing him prosecution on a gun charge remains valid. Prosecutors denied the accusation, saying the agreement was signed by a prosecutor, but probation agents did not sign it, so it never became valid.

The conflict is now in front of U.S. District Judge Maryellen Noreika, who is weighing the prosecution’s motion to pull the tax misdemeanor charges and potentially file them in another court.

Biden's defense attorney on the case, Christopher Clark, also filed to withdraw from the case Tuesday, saying he could be called as a witness over the negotiation and drafting of the deal and cannot also act as his lawyer. He has been replaced by another Hunter Biden attorney, Abbe Lowell.
