Powell, a former federal prosecutor, recently claimed the president's legal team has been receiving a deluge of evidence concerning voter fraud and other irregularities, telling Fox Business that she has enough proof to launch a widespread criminal investigation and that, "we're getting ready to overturn election results in multiple states."

While she declined to detail what evidence she may have in her possession, she insisted, "I don't make comments without having the evidence to back it up."

The Epoch Times' Tom Ozimek reports that Trainor, in his tweet, called Powell "forthright and honest in every case she's ever taken on," adding that, "if she says there is rampant voter fraud in #Election2020, I believe her."

Meanwhile, Trump campaign adviser Corey Lewandowski told "The Water Cooler" podcast that he, too, believes Powell's claim of having evidence of systemic election fraud.

Lewandowski, speaking to podcast host David Brody, called Powell a "dogged professional attorney" and said that "if she says she has that evidence, I have no reason to doubt her at all."

"It's going to be time to start to present that evidence and present it to a court of law," he added.

Powell's claim centers on the notion that elections software switched "millions of votes" from President Donald Trump to Democratic presidential nominee Joe Biden. She said a whistleblower has come forward alleging that the voting software was designed to "rig elections."

"He saw it happen in other countries," she said, apparently referring to election hardware and software by Dominion Voting Systems and Smartmatic, or perhaps other software and machines.
