The links you cite have information which was correct - THEN! However, on 1/10/25 Trump was sentenced by Judge Merchan, having been denied the motion to dismiss the guilty verdict. Normally, criminal defendants do not have a legal right to appeal their verdicts until a final judgement is entered against them, but Merchan allowed it, citing the unprecedented nature of the case. In criminal law, a final judgement must include the defendant's sentence. Accordingly, Merchan moving forward with the sentencing was favorable to Trump because it would result in a final judgement against him - which made it possible for him to properly appeal his CONVICTION.
Other than winning at appeal, there is no mechanism, which can ever erase his 34-count felony conviction or free him from the limitations and restrictions attached to a convicted felon by the State of NY.
