All of the standard fact checking sites, classified the Hunter Biden laptop claims, made during the 2020 US election, as false news and Russian misinformation. This was also said by Joe Biden himself and the Democrat establishment. And, now they are all proven wrong. What this shows is that fact checkers cannot be trusted on issues that may be inconvenient truths to the Left and globalist elites. The Covid plandemic is another example, where these same fact checkers all dismissed the lab origin hypothesis of Covid as an anti-China conspiracy. In fact, it too is likely to be true.
