This is misleading. Federal courts have ruled against Mr. Trump’s assertion.
In August 2020, the League of Women Voters and other groups sued Pennsylvania over a lack of clarity in state policy over mail-in ballots that had been rejected because of issues with the signatures, noting the absence of official guidance or uniform standards. A month later, Pennsylvania’s top election official told county election officials that they could not reject ballots because of a perceived mismatch in signatures. In response, the Trump campaign added a challenge to this guidance to an existing lawsuit.
In October, a federal judge appointed by Mr. Trump ruled against the campaign, writing that the state election code “does not impose a signature comparison requirement.” About two weeks later, the Pennsylvania Supreme Court, which included two Republicans, ruled unanimously that the election code does not require signature verification.
Baseless examples of supposed fraud
What Mr. Trump Said
“In Fulton County, Republican poll watchers were ejected, in some cases, physically from the room under the false pretense of a pipe burst. Water main burst, everybody leave, which we now know was a total lie. Then election officials pull boxes, Democrats, and suitcases of ballots out from under a table.”

A water leak caused a delay for about two hours in vote counting at the State Farm Arena, but no ballots or equipment were damaged. Georgia’s chief election investigator, Frances Watson, testified that a “review of the entire security footage revealed that there were no mystery ballots that were brought in from an unknown location and hidden under tables.”
Election observers and journalists were present at State Farm Arena when the water leak occurred. They were not asked to leave, Ms. Watson said, but simply “left on their own” when they saw one group of workers, who had completed their task, exit.
