In a dramatic scene in court, the plea deal struck by Hunter Biden fell apart amid the judge's concerns over the terms of the agreement.

Hunter Biden pleaded not guilty to the charges.

U.S. District Judge Maryellen Noreika had raised concerns about the parties linking the tax plea agreement to the deal on the gun charge, and over whether or not a provision in the deal would grant Hunter Biden blanket immunity, meaning that the government would not prosecute him further.

There is no plea deal in the Hunter Biden case.

A deal between federal prosecutors and Hunter Biden is in jeopardy of falling apart.

There is now a brief recess as the parties try to come to terms.
