Former President Donald Trump released a statement about the Supreme Court's presidential immunity decision in a post on his social media platform.

"BIG WIN FOR OUR CONSTITUTION AND DEMOCRACY. PROUD TO BE AN AMERICAN!" Trump wrote on Monday morning.

A senior Biden campaign advisor released a statement about the court's ruling on immunity, stating "Today’s ruling doesn’t change the facts, so let’s be very clear about what happened on January 6: Donald Trump snapped after he lost the 2020 election and encouraged a mob to overthrow the results of a free and fair election."

The campaign argued that Trump "thinks he’s above the law and is willing to do anything to gain and hold onto power for himself."

The Supreme Court ruled 6-3 on the immunity case against former President Donald Trump stating, "The President enjoys no immunity for his unofficial acts, and not everything the President does is official.

The ruling, in which all of the liberal justices dissented, added, "The President is not above the law. But under our system of separated powers, the President may not be prosecuted for exercising his core constitutional powers, and he is entitled to at least presumptive immunity from prosecution for his official acts."

With the Supreme Court poised to rule in Trump’s presidential immunity case, former President Donald Trump is continuing to push his defense, saying Monday's decision with be a "big" and "important" one.

“It is a BIG decision, an important decision, a decision which can affect the Success or Failure of our Country for decades to come. We want a GREAT Country, not a weak, withering, and ineffective one. STRONG PRESIDENTIAL IMMUNITY IS A MUST!” Trump posted on his social media platform on Sunday.

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.
