'Shocking': Ex-prosecutor slams Trump's SCOTUS claim he has 'voluminous' evidence of fraud

In his effort to prove to the U.S. Supreme Court that presidents should be immune from criminal prosecution, Donald Trump on Tuesday touted that he had "voluminous information" that the 2020 presidential election was "tainted by extensive fraud and irregularities."

But the claim that the former president had ample proof that his reelection was being usurped in favor of Democratic nominee Joe Biden doesn't square with former federal prosecutor Andrew Weissmann.

He slammed it as "pretty shocking" and an "unsupportive assertion."

Trump's legal brief filed with the court Tuesday reads, "President Trump communicated with the Vice President, the Vice President’s official staff, and members of Congress to urge them to exercise their official duties in the election certification process in accordance with the position, based on voluminous information available to President Trump in his official capacity, that the election was tainted by extensive fraud and irregularities."

Trump's argument that as president he should be retroactively granted absolute immunity for his maneuvers to sway the results of the election that led to the deadly riot on the Capitol on Jan. 6 2020 was echoed again in the filing, which suggested that, if the Supreme Court doesn't accept his argument, it would "incapacitate every future president."

The document comes in advance of oral arguments scheduled for April 25.

Trump's attorneys wrote: "The president cannot function, and the presidency itself cannot retain its vital independence, if the president faces criminal prosecution for official acts once he leaves office."

So far, the former president has lost the argument in two different courts.

Trump is trying to push on Jan. 6 he had been acting in his capacity as president, keeping communications with Vice President Mike Pence and his staff as well as Congress members.

But again, Weissmann notes the mentions, opining about Pence "of all people," and submits: "No hard evidence cited."

Among the masses that charged towards the Capitol following Trump's speech during a "Stop The Steal" rally, many had broken into chants of “Hang Mike Pence!” after it was learned the vice president was going to move ahead and accept electoral votes that deemed Biden the winner of the contest.
