“The Court finds that instances of voter fraud are relevant to the claims and defenses in this case,” District Judge J. Nicholas Ranjan wrote on Thursday, telling Republicans that they need to provide evidence of fraud to the Democratic Party and the Sierra Club, which are part of the lawsuit.

The Democrats had asked for information and documents that would show steps the Republicans took to study the possibility of fraud, especially related to the use of dropboxes, ballot collection and mailed-in ballots in the primary elections.

The Trump campaign and Republicans had refused to do so. But with Thursday’s court order, they must answer questions from the Democratic groups and turn over records of communications — or say they have none. The Trump campaign has until Friday to respond, the judge said.

The Trump campaign “should not be permitted to raise such spectacular fraud related claims, particular in this national climate,” lawyers representing the Democrats wrote.
