Sure, but elected officials in Congress will lie for their own reasons. The actual people who are scientists who work for the government do not believe this virus ever came from a lab, and there has never been any evidence it was ever in a lab before isolation from wild type strains in circulation between humans. The opinion of the actual experts is that it originated in the wild and was not leaked from a lab, and, again, there is precisely zero evidence pointing in another direction. None of that is personal opinion, it's all just raw facts. If I was to state my personal opinion I'd say that some Republicans in Congress are either stupid enough to believe a lie which doesn't have evidence or don't care about the truth, because their political party tolerates and even encourages politicians to make dishonest statements which confirm the priors of their political base, which is largely composed of rubes without critical thinking abilities. But that's all opinion. What's fact is that there isn't any evidence of it being at all man made and that the vast majority of experts agree it was a completely wild virus.

They're right. That's misinformation. It's coming from US officials, but it's still misinformation. I hate to break it to you, but politicians lie sometimes.
