Former President Donald Trump's campaign sent out an email fundraising off the Supreme Court decision on presidential immunity.

"BREAKING FROM TRUMP: Supreme Court gives TOTAL IMMUNITY for official acts!" Trump campaign's fundraising email said.

"Official acts cannot be illegally prosecuted - BIG WIN FOR DEMOCRACY &; OUR CONSTITUTION!" the fundraising email continues, calling the case a "witch hunt" and saying it "should've never happened."

Justice Ketanji Brown Jackson issued a dissent in the Supreme Court's presidential immunity ruling arguing it "breaks new and dangerous ground."

"So, how does this new Presidential accountability model work? An initial problem is the lack of clarity regarding what this new model entails," she wrote.

Jackson added that the ruling "unilaterally altered the balance of power between the three coordinate branches of our Government as it relates to the Rule of Law, aggrandizing power in the Judiciary and the Executive, to the detriment of Congress."

Jackson and Justice Sonia Sotomayor both penned dissents. Justice Elena Kagan joined Sotomayor in her dissent.

The split 6-3 opinion was authored by Chief Justice John Roberts.

In her dissent, Justice Sonia Sotomayor pushed back against the conservative justices' ruling on former President Donald Trump's immunity case.

Sotomayor contended in her dissent that the ruling "makes a mockery of the principle, foundational to our Constitution and system of Government, that no man is above the law."

She argued the conservative justices invented "an atextual, ahistorical, and unjustifiable immunity that puts the President above the law."

"That holding, which will prevent the Government from using a President's official acts to prove knowledge or intent in prosecuting private offenses, is nonsensical. Argument by argument, the majority invents immunity through brute force," she added.

Sotomayor also said the ruling opens up the possibility that when a president uses their official powers in any way, they will be "insulated from criminal prosecution."

"Orders the Navy's Seal Team 6 to assassinate a political rival? Immune. Organizes a military coup to hold onto power? Immune. Takes a bribe in exchange for a pardon? Immune. Immune, immune, immune," Sotomayor wrote.

Justices Elena Kagan and Ketanji Brown Jackson joined Sotomayor in her dissent.

The split 6-3 opinion was authored by Chief Justice John Roberts.

Special counsel Jack Smith's office declined to comment on the Supreme Court ruling, a spokesperson told ABC News.

The court's ruling will affect whether former President Donald Trump faces a federal trial this year on four felony counts brought by Smith, including conspiracy to defraud the U.S. and obstruction of an official proceeding, for his attempts to overturn his 2020 election loss to President Joe Biden.

In their dissents, both justices Sotomayor and Jackson addressed the question of whether a president would have immunity from criminal prosecution for acts of murder -- including ordering the assassination of a political rival.

In their dissents, both Sotomayor and Jackson addressed the question of whether a president would have immunity from criminal prosecution for acts of murder -- including ordering the assassination of a political rival.

When the president "uses his official powers in any way, under the majority's reasoning, he now will be insulated from criminal prosecution," Sotomayor said in her dissent. "Orders the Navy's Seal Team 6 to assassinate a political rival? Immune."

ABC News Supreme Court contributor Kate Shaw said on ABC News Live Monday that she agreed with the dissenting opinion that ordering the hypothetical assassination could be considered immune from criminal prosecution.

"In terms of the application of this immunity to very extreme scenarios like ordering an assassination, I'm not sure the majority successfully explains why this rule would not shield that kind of conduct if it's engaged in an official capacity, even if it's wildly wrong and dangerous and destructive," she said. "If that conduct is done in official capacity, I think the dissent is right on this opinion's own logic. It would be immune, and that is a genuinely chilling implication of this case."

The SEAL Team 6 assassination hypothetical was raised during oral arguments on the case in April.

Sotomayor raised it first while questioning Trump attorney John Sauer. She pointed back to an earlier exchange Sauer had in a lower court proceeding.

"I'm going to give you a chance to say ... if you stay by it: If the president decides that his rival is a corrupt person and he orders the military, or orders someone, to assassinate him -- is that within his official acts for which he can get immunity?" she asked during oral arguments.

"It would depend on the hypothetical," Sauer answered. "We could see that could well be an official act."
