I always find it amusing, no depressing, how the Left fact checkers have their own biases that are never disclosed, at least by them.

“Twitter for the first time put a fact-check label on tweets from President Trump, using the controversial tactic on messages in which the president complained there is “no way” that “mail-in ballots will be anything less than substantially fraudulent.” It may be instructive that Twitter seized on the mail-in balloting tweets as the first issue from Trump’s rapid fire social media feed to slap with a fact-check label. Twitter did not disclose in its so-called fact-check it is partners with two groups financed by leftist donors that engage in voter participation efforts, including drives pushing mail-in balloting. Twitter sits on the “Premier Partner” list of one of those groups alongside ViacomCBS, the merger of Viacom and CBS. Twitter’s so-called fact-check about Trump’s mail-in balloting cited CBS political reporter Grace Segers vouching for mail-in voting. Analysts have posited such proposals help the Democratic Party. Republicans specifically fear the prospect of voter fraud, since mail-in voting would be harder to authenticate.

     Breitbart and Natural News.com covered the issue of electoral fraud by the Democrats in 2016, and there are other sites that fully support Trump. It is utterly depressing that Trump has done nothing about this right up to now. Anyone would think that he was a plant, just wanting to fail. Or be watered. Or violently pulled up and tossed away.
