The morning after being indicted for the fourth time this year, former President Donald Trump on Tuesday promised to present a “Large, Complex, Detailed but Irrefutable” report that will prove there was fraud in the 2020 presidential election in Georgia.

Trump said he will discuss the report during a news conference Monday in Bedminster, New Jersey.

“Based on the results of this CONCLUSIVE Report, all charges should be dropped against me & others - There will be a complete EXONERATION!” Trump wrote Tuesday on his Truth Social platform. “They never went after those that Rigged the Election. They only went after those that fought to find the RIGGERS!”

Whether Trump truly believes the election was stolen could be at the heart of his criminal defenses in the Georgia and federal cases that accuse the former president and his allies of scheming to illegally overturn Joe Biden’s win in 2020. 

The indictments in both cases allege Trump knowingly made false claims about election fraud.

The former president continues to insist the election was stolen and has pleaded not guilty in the federal case. In Georgia, the charges he faces include violating the state's racketeering act, soliciting a public officer to violate their oath and making false statements.

This is not the first time Trump has promised a report that would prove his claims. Previous attempts, however, have failed to deliver, although some have given unsubstantiated fodder to conspiracy theorists. 

Trump and his allies failed to prove their case in more than 60 lawsuits challenging the election results. The Department of Homeland Security's Cybersecurity and Infrastructure Security Agency and the National Association of State Election Directors described the 2020 election as “the most secure in American history.” And then-Attorney General William Barr said the Justice Department found no evidence of widespread voter fraud that could have changed the outcome of the election.

Also, a special purpose grand jury in Georgia said it found no evidence of widespread fraud in the state.

In a December 2020 report, a cybersecurity firm, Allied Security Operations Group, said its “forensic audit” in Antrim County, Michigan, found that Dominion voting machines in the county had a 68% error rate. 

Barr testified to the House Jan. 6 committee last year that Trump told him the report was “absolute proof that the Dominion machines were rigged” and it “means that I am going to have a second term.”

But former acting Deputy Attorney General Richard Donoghue noted to the committee that Antrim County conducted a hand recount. He said he calculated the error rate to be .0063%, “which is well within tolerance.”

Barr told the committee the report “looked very amateurish to me” and lacked credentials of the auditors. 

“And the statements were made very conclusory like this — these machines were designed to engage in fraud, or something to that effect. But I didn't see any supporting information for it,” Barr testified. “And I was somewhat demoralized because I thought, boy, if he [Trump] really believes this stuff, he has lost contact with it — he's become detached from reality.”

In 2021, the Republican-led Senate in Arizona initiated an audit of the election in Maricopa County in response to claims about election fraud.

The review was led by Cyber Ninjas, a small Florida cybersecurity firm with no experience auditing elections and whose CEO had publicly promoted conspiracy theories about the election being stolen from Trump, who for months predicted the audit would vindicate him.

The report listed a number of unsupported allegations about irregularities, but in the end, it found Biden won by a larger margin than had been certified. Maricopa County officials blasted the auditors for using methodology they said was flawed and for lacking understanding of federal and state election laws.

In addition, The Washington Post reported in February that the Trump 2020 campaign commissioned an outside research firm in an attempt to prove election-fraud claims, but the firm failed to find evidence that Trump was the rightful winner and disputed many of his theories. The campaign kept the findings secret. 

The review by Berkeley Research Group was conducted in the final weeks of 2020 before the Jan. 6, 2021, Capitol riot, The Post reported.

Trump has repeatedly accused the Justice Department and others of not thoroughly investigating his election-fraud claims. But Donoghue, the former acting deputy attorney general, told the Jan. 6 committee the department conducted “dozens of investigations, hundreds of interviews. The major allegations are not supported by the evidence developed."

Georgia officials have also insisted they’ve investigated fraud claims but found nothing substantial. 

Despite the lack of evidence to support Trump’s claims, a CNN poll conducted last month found that 69% of Republicans and Republican-leaning independents believe Biden’s win was not legitimate.
