But there has been no evidence of impropriety or fraud in Michigan, election officials have said. But election officials across the country have said repeatedly there was no widespread fraud. In Arizona, the Republican Party is pressuring county officials to delay certifying results. In northwestern Arizona, Mohave County officials postponed their certification until next week.

In Michigan, two Republican election officials in the state's largest county initially refused to certify results despite no evidence of fraud. The moves don’t reflect a coordinated effort across the battleground states that broke for Biden, local election officials said. There is no precedent for the Trump team's widespread effort to delay or undermine certification, according to University of Kentucky law professor Joshua Douglas. Across the nation, recounts and court challenges must wrap up and election results be certified by Dec. 8. Trump personal attorney Rudy Giuliani argued to stop vote certification in Pennsylvania on Tuesday, the first time he’d been in a courtroom in decades.
