A federal judge in Pennsylvania ordered the Trump campaign and Republican party to produce evidence to substantiate their claims of mail-in voter fraud. President Donald Trump had said that he will reject the legislation that contains the provision for emergency funding for the postal agency so as to block the ‘mail-in’ vote.

“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, directing the Republicans to provide evidence of fraud to the Democratic Party and the Sierra Club, which are part of the lawsuit.

“If you have none, state as much,” the court said. The hearing of the case will begin in September. Nicholas Ranjan, the judge is a Trump appointee.

The President had been criticising the mail-in voting for months stating that it would lead to “one of the greatest frauds in history.” Mail-in voting is a common process in the US where millions of Americans – including much of the military – have used the post office to cast absentee ballots for years. No case of ‘fraud’ as Trump claims it has been reported yet.

Meanwhile, democrats fear that Trump might eventually hold on to the narrative and might try to steal the election if he loses, in November.
