This is a flat-out misstatement of fact.
The judge threw out the plea arrangement because the prosecutor was attempting to force the judge to be the final arbiter of Hunter Biden’s compliance with the terms of the plea arrangement to determine any future wrongdoing with respect to a possible gun charge against Biden in the future. Also, Republicans were pissed off he wasn’t paying a higher price.
From the article:
U.S. District Court Judge Maryellen Noreika, who was appointed by President Donald Trump, raised multiple concerns about the specifics of the deal and her role in the proceedings. The plan also included an agreement on a separate gun charge — Biden has been accused of possessing a firearm in 2018 as a drug user. As long as he adhered to the terms of his agreement, the gun case was to be wiped from his record. Otherwise, the felony charge carries 10 years in prison.
(Emphasis mine.)
These kinds of deliberately misleading statements such as I quoted from you above is why no one trusts your cites or your rhetoric.
