2024 election live updates: Crowd gathers for Trump's Madison Square Garden rally

A comprehensive audit of Georgia's voter rolls found that just 20 noncitizens were registered to vote on a registration list of over 8 million, according to an announcement Wednesday from Georgia Secretary of State Brad Raffensperger.

All 20 of those registrations have been canceled and referred to the authorities for investigation and potential prosecution, Raffensperger said.

An additional 156 registrations were flagged for a "human investigation" that is now underway.

"Georgia has the cleanest voter list in the entire country," Raffensperger, a Republican, said of the audit. "Georgia can trust in their elections."

The result of the audit stands in stark contrast to claims being pushed by some Republicans, including former President Donald Trump, that large numbers of noncitizens are going to vote in the 2024 election.

Harris swiped at Trump's past comment about being a dictator only on "Day One" and his more recent threat to use the military against political opponents.

"Donald Trump is increasingly unhinged and unstable," she said. "And in a second term, people like John Kelly would not be there to be the guardrails against his propensities and his actions. Those who once tried to stop him from pursuing his worst impulses would no longer be there, and no longer be there to rein him in."

Harris did not take any questions after she finished the brief remarks.

Kelly claimed Trump said he wanted generals like the ones Adolf Hitler had, and that, in his view as a retired general, the former president fell under the definition of a "fascist."

"It is deeply troubling and incredibly dangerous that Donald Trump would invoke Adolf Hitler, the man who is responsible for the deaths of 6 million Jews and hundreds of thousands of Americans," Harris said. "All of this is further evidence for the American people of who Donald Trump really is."

"The bottom line is this. We know what Donald Trump wants. He wants unchecked power," Harris added. "The question in the next 13 days will be: What do the American people want?"

The Harris campaign seized on former White House chief of staff and ex-Marine general John Kelly's remarks panning Trump as a "fascist," among other things, convening a press call of former GOP military leaders to sound a similar alarm.

"This is a difficult conversation for me as a lifelong Republican who always, you know, supported the Republican Party until Donald Trump came along," Brig. Gen. Steve Anderson said.

Anderson mocked the fact that Trump "couldn't qualify to be in the military -- he has 34 felony convictions -- so, how can we have the commander-in-chief be in charge of a military that he couldn't possibly join?"

Kevin Carroll, who served as senior counsel to Kelly when he was Homeland Security secretary under Trump, also underscored the seriousness of Kelly's surprisingly public rebuke of his old boss.

"I had the honor of working aside him, and I know him speaking out this way was no small step for him," Carroll said.
