Shortly after the Supreme Court ruled Monday on Trump's immunity case, the Biden reelection campaign organized a group of surrogates on a press call to lambast the decision that makes the former president immune from federal prosecution for official actions he took while in office.

The group included Capitol police officer Harry Dunn, New York Rep. Dan Goldman and Texas Rep. Jasmine Crockett. The group criticized the Republican-majority Supreme Court for giving the former president "untethered political power," or freedom to act as a "dictator."

"I do think that it was extremely scary," said principal deputy campaign manager Quentin Fulks, who led the call. "So what happens if there's an election outcome [or] result that Trump doesn't like in a Senate race, or governor's race or House race?"

The campaign said that Biden would be out on the campaign trail to highlight the threat that Trump poses to democracy following this decision.

"The Supreme Court just handed Donald Trump three keys to absolute immunity as president of the United States and so we're going to continue to point out to voters," Fulks said. "When Trump says these things, now he will have the ability to do them if he is the president or reelected president of the United States, and we have to do everything in our power to stop."

Fulks diverted attention from a question about Biden's debate performance, saying the Supreme Court's decision was a "reality check" in the face of debate night.

"Now until November, we're going to continue taking this case directly to voters who are going to decide this election," he said.

Several Republicans and Democrats on Capitol Hill spoke out about the Supreme Court's ruling on presidential immunity.

Many GOP members of Congress lauded the decision and said it was a victory for former President Donald Trump. Meanwhile, many Democrats on the Hill said it sets a dangerous precedent.

Speaker Mike Johnson said the decision marks "another defeat for President [Joe] Biden’s weaponized Department of Justice and Jack Smith."

"As President Trump has repeatedly said, the American people, not President Biden’s bureaucrats, will decide the November 5th election," Johnson said in a statement.

House Minority Leader Hakeem Jeffries said in a statement that the immunity SCOTUS decision “sets a dangerous precedent for the future of our nation.”

“House Democrats will engage in aggressive oversight and legislative activity with respect to the Supreme Court to ensure that the extreme, far-right justices in the majority are brought into compliance with the Constitution,” he said.

Senate Majority Leader Chuck Schumer said in a series of statements on X that the ruling was a "disgraceful decision by the MAGA SCOTUS."

"The very basis of our judicial system is that no one is above the law. Treason or incitement of an insurrection should not be considered a core constitutional power afforded to a president," he said.

Sen. Marsha Blackburn, R-Tenn., said on a post on X that the ruling "upholds the rule of law in our country and rebukes Democrats’ blatant attempts to weaponize our legal system against Donald Trump."

"Time and time again, Americans have watched the Biden administration do everything in its power to take down President Trump, but this partisan attack will not stand in America," she said.

Trump spoke about the ruling in another post on his social media platform arguing that the Supreme Court's decision "should end all of Crooked Joe Biden’s Witch Hunts against me."

The former president specifically cited his Manhattan hush-money case, in which Trump was charged with 34 counts of falsifying business records. He is slated to be sentenced this month in the hush-money case.

Trump also cited the New York attorney general civil case against his businesses' fraudulent practices and the E. Jean Carroll defamation case.

Although Justice Amy Coney Barrett sided with the majority on the presidential immunity case, she dissented on a section of the ruling that limits what evidence can be used against a president at trial.

Barrett brought up a hypothetical situation of a bribery case against a president, arguing while there are clear federal laws that prohibit the commander in chief from accepting bribes, excluding evidence would "hamstring the prosecution."

"To make sense of charges alleging a quid pro quo, the jury must be allowed to hear about both the quid and the quo, even if the quo, standing alone, could not be a basis for the President’s criminal liability," she wrote in her concurring opinion.

"I appreciate the Court’s concern that allowing into evidence official acts for which the President cannot be held criminally liable may prejudice the jury ... But the rules of evidence are equipped to handle that concern on a case-by-case basis," Barrett added.

The heads of the Republican National Committee and Democratic National Committee both released statements following the Supreme Court's immunity ruling.

RNC chair Michael Whatley said "today's ruling is a victory for the rule of law and a reminder that the Constitution outweighs the left's weaponization of the judicial system against President Trump and his allies."

DNC Chair Jamie Harrison, however, argued the "ruling only underscores the stakes of this election," in light of Trump's repeated threats against his opponents.

"The only thing standing between Donald Trump and his threats to our democracy is President Biden -- and the American people will stand once again on the side of democracy this November," he said.
