Can you be more specific? What specific claims were labeled as disinformation by whom?

This matters because what was covered at the time was that the laptop was known not to have a good chain of custody. At the time, journalists at the NYT, WaPo, and others reported that they were able to verify some of the emails but that large amounts of data were hard to validate and the lack of a clean forensic history made it hard to confirm validity for many of the files because there were clear signs of access and modification after it had left Hunter Biden’s control. Nothing which has come out since then has changed that, and the general consensus outside of movement conservatives seems to be that the main thing politicizing this did is to make it harder for the DOJ and other investigators to prove anything to a legal standard.
