affirming Mr. Biden’s victory in the recent White House race will be counted and made official. Mr. Trump and Mr. Flynn are among prominent Republicans who allege the race was rigged and not really won by Mr. Biden, but no credible evidence has emerged to corroborate their claims. Mr. Flynn, a former Army lieutenant general, made the post about protesting in response to the president alluding on Twitter earlier Saturday to a rally his supporters plan to hold in Washington. “The ‘Justice’ Department and the FBI have done nothing about the 2020 Presidential Election Voter Fraud, the biggest SCAM in our nation’s history, despite overwhelming evidence. They should be ashamed. History will remember. Never give up. See everyone in D.C. on January 6th,” Mr. Trump said on Twitter. “I know a thing or two about the ‘Just Us’ department,” replied Mr. Flynn, one of several Trump allies charged in the investigation into the 2016 race led by former special counsel Robert S. Mueller.
