Yes, fact it is. Many experts attested to the facts of the theft. They did so in testimony before state legislators in the states where the election was stolen. The hours of expert testimony were available online. I linked to some of it. A search of this website's archives would provide it or else provide evidence that the evidence was taken down by Google, YouTube, and the other censors.
You need to ask yourself why information that is contrary to the official narrative is taken down. If the information is wrong, the facts won't support it, so why bother to censor it? The answer is that the information is correct, and we are not allowed to hear it and make up our own minds. The bought-and-paid-presstitutes are hired to tell us what to believe. Far too many Americans permit the corrupt presstitutes to control their minds.
The Democrats know that they stole the election. That is why they go to court in efforts to block legitimate investigations as "racist" or "lack of standing." Why would Biden's US Attorney General be suing the State of Georgia for legislating electoral reforms that require an ID to vote if Democrats don't intend to use the same election fraud to steal future elections? https://www.rt.com/usa/527635-doj-georgia-voting-laws/
