Probe Finds 650,000 Facebook Posts Attacking Election Before Capitol Riot

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 President Donald Trump voiced as they stormed the Capitol, demanding he get a second term.
