Facebook groups swelled with at least 650,000 posts attacking the legitimacy of Joe Biden’s victory between Election Day and the Jan. 6 siege of the U.S. Capitol, with many calling for executions or other political violence, an investigation by ProPublica and The Washington Post has found.
The barrage — averaging at least 10,000 posts a day, a scale not reported previously — turned the groups into incubators for the baseless claims supporters of then-President Donald Trump voiced as they stormed the Capitol, demanding he get a second term. Many posts portrayed Biden’s election as the result of widespread fraud that required extraordinary action — including the use of force — to prevent the nation from falling into the hands of traitors.
