The three-hour hearing featured several turbulent interludes. Noreika's line of questioning about the possible immunity agreement exposed fissures between the two parties, and the discussion culminated in prosecutors threatening to bring charges under the Foreign Agents Registration Act.
That prompted Chris Clark, an attorney for Biden, to say: "As far as I'm concerned, the plea agreement is null and void" -- stirring the courtroom into audible gasps.
After a brief recess, the parties moved past those disagreements. Clark acquiesced to the government's position that any immunity of Hunter Biden would only include tax, firearm, and drug-related conduct investigated by the government.
For the next 30 minutes, the parties fell into a pattern of negotiation, consulting in the middle of the courtroom with opposing counsel, retreating to their corners to discuss, and repeating.
At one point, a visibly frazzled Clark approached prosecutors with arms stretched wide, threatening to "rip it up" and looking to U.S. Attorney David Weiss, another Trump appointee. "Does anyone want to talk about this?" Clark said.
"Really bad for everyone ... no good," Clark was overheard telling prosecutors moments later.
The dispute seemed to arrive at something of an impasse.
During one recess, as the parties awaited the judge's return to the bench, Abbe Lowell, a seasoned defense attorney who is handling other matters for Hunter Biden, approached Weiss and introduced himself. "Looks like I'm going to be involved in the fray now," he said, before shaking his hand and returning to his seat in the gallery.
Meanwhile, a visibly agitated Hunter Biden transitioned from sitting to standing, summoning various members of his legal team to discuss developments, and consulting with Clark. Across the room, Weiss appeared to share Hunter Biden's demeanor.
