NYT:

Sidney Powell, a lawyer who was part of President Trump’s legal team, spread a conspiracy theory last month about election fraud. For days, she claimed that she would “release the Kraken” by showing voluminous evidence that Mr. Trump had won the election by a landslide.

But after her assertions were widely derided and failed to gain legal traction, Ms. Powell started talking about a new topic. On Dec. 4, she posted a link on Twitter with misinformation that said that the population would be split into the vaccinated and the unvaccinated and that “big government” could surveil those who were unvaccinated….

Ms. Powell’s changing tune was part of a broader shift in online misinformation. As Mr. Trump’s challenges to the election’s results have been knocked down and the Electoral College has affirmed President-elect Joseph R. Biden Jr.’s win, voter fraud misinformation has subsided. Instead, peddlers of online falsehoods are ramping up lies about the Covid-19 vaccines, which were administered to Americans for the first time this week.
