Sen. John Fetterman (D-Pa.) on Sunday mocked former President Trump’s recent claims surrounding the validity of election results.

“It’s the same s— that he played in ‘20, and that didn’t go anywhere,” he told CNN’s Dana Bash on “State of the Union.”

Trump has recently been sowing doubt when it comes to election results in Fetterman’s home state of Pennsylvania.

“Pennsylvania is cheating, and getting caught, at large scale levels rarely seen before. REPORT CHEATING TO AUTHORITIES. Law Enforcement must act, NOW!” Trump wrote Wednesday on Truth Social.

Trump and allies have continually spread unfounded claims about the 2020 election, with the former president consistently refusing to accept his loss in the presidential election four years ago.

“It’s the same thing that he tried in 2020 and, you know, we had … absolutely a secure election,” Fetterman said in his Sunday CNN appearance. “And now, there was voter fraud in Pennsylvania, and it was a handful of Republicans, and they had, they had their dead moms voting for Trump.”

“And I’d like to remind everybody that they were all caught and they were prosecuted,” he continued.

In an average of polls from The Hill/Decision Desk HQ, Trump is ahead of Harris by 0.7 points, with the former president garnering 48.8 percent support and the vice president garnering 48.1 percent.

“I’d like to remind everybody that Biden wrecked his s— by 80,000 votes, and now we’re gonna be back in the same situation, he’s gonna try to lie and claim these baseless things, but now we’re gonna have a new team leading America, and that’s gonna Harris and Walz, but it is gonna be close,” Fetterman said of Trump.

Polling from The New York Times/Philadelphia Inquirer/Siena College released Sunday found Harris and Trump tied in the Keystone State at 48 percent support from likely voters.

In an emailed statement sent Sunday to The Hill, Republican National Committee (RNC) spokesperson Claire Zunk said “President Trump’s unprecedented election integrity operation is committed to defending the law and protecting every legal vote.”

“We have engaged, and won, in record numbers of legal battles to secure our election. With over 230,000 volunteers to Protect the Vote, this is the most robust election integrity operation the party has ever seen,” Zunk continued. “We have stopped Democrat schemes to dismantle election safeguards and will continue to fight for a fair and transparent election for all Americans.”

The Hill has reached out to the Trump campaign for comment.
