Former President Donald Trump proclaimed Saturday he “will never yield” to President Biden’s “Stalinist” tactics, in his first live comments since the unsealing of a 49-page, 37-count federal indictment on charges of mishandling classified documents.

“They tried to frame me for treason and now they’re trying to do it again,” a defiant Trump said in an often rambling 84-minute speech before a crowd of more than 3,500 Republican state party delegates and guests at the Columbus Convention and Trade Center in Columbus, Ga.

“Biden is trying to jail his leading political opponent … just like they do in Stalinist Russia or in communist China,” Trump railed.

But he also poked fun at what he dismissed as “ridiculous” and “baseless” charges that have been brought against him.

“We stand up to the radical left Democrats and their lawless partisan prosecutors,” he said – adding as an aside, “Every time I fly over a blue state, I get a subpoena. ‘Put him before the grand jury!’”

“I never thought such a thing could happen in America.”

“I’ve put everything on the line for you and I will never yield,” he promised at the state’s annual GOP convention — held sans Gov. Brian Kemp, a longtime Trump critic.

“I’m the only candidate who has what it takes to smash this corrupt system,” he said.

Trump slammed Biden repeatedly, blaming him for the ruinous economy and weakness on the world stage.

“If you took the worst five presidents in the history of the United States and added them up. they would not have done near the destruction to our country as Joe Biden has done,” Trump said.

“We are a nation in decline, and now these radical left lunatics want to interfere with our elections by using law enforcement,” he declared, referring again to the federal cases against him.

“It’s totally corrupt and we can’t let it happen,” he said. “We will drive out the globalists, we will cast out the communists, and we will throw off the sick political class that hates our country.”

It was the first of two campaign-style stops for Trump, who remains the front-runner in the Republican presidential primary race despite his cascading legal woes.

He later vowed to stay in the race even if he is convicted, telling Politico “I’ll never leave.”

And if he was eventually convicted, Trump dodged the idea he’d be forced to pardon himself from the White House should he prove victorious in 2024.

  “I don’t think I’ll ever have to,” Trump told the outlet. “I didn’t do anything wrong.”

“Nobody wants to be indicted,” he added. “I don’t care that my poll numbers went up by a lot. I don’t want to be indicted. I’ve never been indicted. I went through my whole life, now I get indicted every two months. It’s been political.”

The case unsealed in Miami on Friday came after a federal grand jury heard evidence that Trump illicitly retained classified documents and kept them at his Mar-a-Lago home.

The charges, including the willful retention of national defense documents and conspiring to obstruct justice, follow Manhattan District Attorney Alvin Bragg’s April indictment for Trump’s alleged falsification of business records.

“We didn’t do any obstruction,” Trump insisted in his speech, in which he debuted a new nickname – “Deranged Jack Smith” – for the special prosecutor who brought Friday’s indictment against him.

“They take one charge and they turned it into 36 charges,” Trump complained.

“We have a thug who’s in charge,” he said, referring to Smith. “This is a political hit job,” he added, carried out by “a sick nest of people that needs to be cleaned out immediately.”

Those two cases may soon be joined by additional indictments: in Georgia over accusations of election interference, and in Washington, D.C. for the former president’s actions surrounding the Jan. 6 Capitol riot.

Trump addressed the Georgia investigation – which reportedly focuses on his 2020 phone calls to Georgia Secretary of State Brad Raffensperger in the wake of his election loss — at length Saturday.

“I was complaining about an election that I thought was rigged, complaining to the proper authorities,” he said. “And the day you’re not allowed to complain about an election, we are in communist China.”

In messages to supporters Saturday, Trump sought to use the prosecutions as fuel for his quest to win the Republican presidential nomination once again.

“I could throw in the towel tomorrow, close down my 2024 presidential campaign, and all charges against me would magically be dropped!” he wrote in a fundraising email.

Doing so, he added, “would be turning my back on our country” — casting his expected Tuesday arraignment as an attack on America itself.

Meanwhile, Trump made a string of posts on social media, including one all-caps missive claiming that “AMERICA WENT TO SLEEP LAST NIGHT WITH TEARS IN ITS EYES” over the indictment, which some Republicans have denounced as a politically motivated power grab.

But Kemp’s pointed absence signaled rifts within the Republican Party over Trump’s candidacy, particularly in the must-win swing state of Georgia, which the former president narrowly lost to President Biden in 2020.

A poll released Friday by Kemp’s Hardworking Americans PAC found that Trump would have the support of just 42% of likely Georgia voters in a rematch against Biden — fully six points less than the 48% support that a generic Republican candidate would receive in such a race.

The statewide survey of 600 voters, taken before news of the indictment dropped, found that Trump would barely edge out Biden 42% to 41% if the presidential election was held today, while any other GOP candidate would beat the incumbent by 10 points, 48% to 38%.

The poll had a 4% margin of error.

After the Georgia speech, Trump was scheduled to head to North Carolina to campaign at that state’s annual Republican convention.
