Hunter Biden hearing: No plea as judge refuses to 'rubber-stamp' deal

House Speaker Kevin McCarthy reacted Wednesday to Hunter Biden's plea dealing being deferred for the time being.

He reiterated his allegation that the president's son has received different treatment from prosecutors, which the Department of Justice has pushed back on.

"There shouldn't be two justice systems in America, and hopefully today that's what is being done," McCarthy said.

"So now is the window to show that we have equal justice, and that's the real question ... is it going to be fair as you treat every other American? That will be the question," McCarthy said as he left the House floor.

Connecticut Sen. Richard Blumenthal, a Democrat, said Wednesday that he hoped Hunter Biden will "acknowledge his responsibility for the proceeding" and that the outcome will be "fair and just."

At the top of her briefing on Wednesday afternoon, White House press secretary Karine Jean-Pierre commented on "the news in Delaware today," as she called it, emphasizing that "Hunter Biden is a private citizen ... this was a personal matter for him," and saying the case was handled by a prosecutor appointed by former President Trump.

"As we have said, the president, the first lady, they love their son and they support him as he continues to rebuild his life," Jean-Pierre said. "This case was handled independently, as all of you know, by the Justice Department."

Judge Noreika scrutinized nearly every facet of the plea deal before deciding to defer the agreement so the parties could reconvene at a later date.

The hearing was punctuated by multiple recesses, during which lawyers scrambled to negotiate their way out of the deal's divergent perspectives.

A visibly agitated Hunter Biden spent much of the time shifting between sitting and standing, summoning members of his legal team to discuss developments. Across the room, U.S. Attorney David Weiss appeared to share his demeanor.

Toward the end of the hearing, Noreika herself lashed out, repeatedly saying she felt as though she was being asked to "rubber-stamp" the deal.

In the end, she did not.

U.S. Judge Maryellen Noreika deferred the plea deal negotiated by Hunter Biden's attorneys and federal prosecutors after a contentious hearing, taking issue with the structure of the arrangement and lamenting on multiple occasions the deal's "form over substance."

In the interim, Hunter Biden entered a not guilty plea. Noreika requested additional briefings from the parties in the coming weeks before determining next steps.

"I'm not going to say I'm going to accept the agreement, I'm not going to say I'll deny it," she said.

The three-hour hearing featured several turbulent interludes. Noreika's line of questioning about an immunity agreement exposed fissures between the two parties, with the discussion culminating in prosecutors threatening to bring foreign agent charges, prompting Chris Clark, an attorney for Biden, to say: "As far as I'm concerned, the plea agreement is null and void."

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.

Judge Noreika asked the parties to consult and brief her in the coming weeks.

In the understatement of the day, Noreika acknowledged that her probing threw "a little bit of a curveball" into the proceeding.
