FEC chairwoman challenges Trump: Put up or shut up, dude. (VIDEO)

Federal Election Commission chairwoman Ellen Weintraub just completely dismissed President Donald Trump's assertion that there was widespread voter fraud in the 2016 election.

"There is no evidence of rampant voter fraud in 2016 or really in any previous election." Weintraub told CNN on Monday.

“People have studied this. Academics have studied this. Lawyers have studied this. The government has studied this. Democrats have studied this. Republicans have studied this,” she continued. “And no one can find any evidence of rampant voter fraud either historically or particularly in the 2016 elections.”

"I think it is damaging to our democracy to spread information like that if there is no proof."

She's even challenging him to show proof, but the White House hasn't really taken her up on this yet.

In a letter to Trump just before the weekend, Weintraub wrote to the president "to provide any evidence" that his claims are true. “To put it in terms a former casino operator should understand: There comes a time when you need to lay your cards on the table or fold."

Trump has continued to claim that voter fraud is what caused him to lose the popular vote. He even had to disband a voter fraud panel after no evidence of fraud showed up, which was officially called the Presidential Advisory Commission on Election Integrity.

Oddly, when Democrats requested for the panel to share their internal working documents (who knows what those could hold) the Trump White House chose to disband instead. It was almost as if the panel itself was the fraud. But, we already knew that.

Trump stated at his latest rally in New Hampshire that the state's four electoral votes would have gone to him if it weren't for this mysterious voter fraud that Trump himself no longer wants to even investigate.

"It was taken away from us," he told the crowd.
