Arizona
Three days after the election, the Trump campaign and the RNC asked an Arizona judge to join a joint lawsuit alleging that voting tabulation in Phoenix was tampered with after some voter’s ballots were unable to be counted because of county-issued sharpie pens which damaged their ballots. On Nov. 7 the attorneys who challenged the use of the sharpies informed judges they are dismissing their case.
That same day the Trump campaign and the RNC filed lawsuits regarding rejected ballots in Maricopa County(Phoenix). The suit alleged that in-person votes were disregarded because of inaccurate guidance from poll workers. Nearly a week later the Trump campaign dropped the suit.
On Nov. 13 the Republican National party of Arizona filed a lawsuit against multiple county officials seeking a hand recount of ballots by precinct instead of by voting centers. The case is currently pending.
