The Race for President and the Power of the presidency colliding in one Supreme Court decision. The Court ruled today that a President has at least some immunity from prosecution. The landmark ruling involves the federal election interference case against former President Donald Trump, brought by special prosecutor Jack Smith. On one hand, the Court ruling that Mr. Trump cannot be prosecuted for official acts, but also saying he is not immune from prosecution for acts outside side of scope as President. Today's 6:00 to 3:00 decision hailed by Mr. Trump as a, Big win for our Constitution and democracy. President Biden speaking tonight on this very issue. But first, here's Laura Jarrett with more on today's Pivotal decision.

Tonight, a monumental win at the Supreme Court for former President Trump. The conservative majority finding the presumptive GOP nominee must receive sweeping immunity for any official acts taken during his presidency, the 6-3 ruling a defeat for Special Counsel Jack Smith, with the court bulldozing through the charges against Mr. Trump for his alleged criminal efforts to stay in power, making the completion of any trial before November virtually impossible. President Biden speaking late tonight.

Today's decision almost certainly means that there are virtually no limits on what the President can do.

Chief Justice John Roberts laying out a new sliding scale of what can be prosecuted, saying a a President may not be prosecuted for exercising his core constitutional powers, that he has immunity from prosecution for all his official acts, but that a President has no immunity for private unofficial acts, while cautioning the President is not above the law. A federal grand jury indicted the former President for orchestrating a conspiracy to retake the White House. Prosecutors alleging he leaned on his DOJ, VP, and state officials to help him reverse the election results, mobilizing meetings of take electors, it all culminating in the violent attack on the Capitol on January 6. Mr. Trump has pleaded not guilty to all charges and argued without immunity, every President could be prosecuted by political opponents.

If you don't have immunity, you're not going to do anything. You're going to become a ceremonial President. You're not going to take any of the risks.

The majority today agreeing the Commander-in-Chief must be able to carry out his constitutional duties without risk of political prosecution. Writing, Without immunity, such types of prosecutions of ex-presidents could quickly become routine, and that would weaken the presidency, which is exactly what the framers intended to avoid. The special counsel had pushed to get the case to trial before November.

My office will seek a speedy trial.

The ruling now dramatically chipping away at parts of Smith's case. The justice is finding Mr. Trump's urging the then attorney general to investigate voter fraud, now absolutely immune from prosecution. What remains in the indictment, including his pressure on his former VP.

Mike Pence is going to have to come through for us.

Are now entitled to a presumption of immunity. The liberal justice is with a blistering pushback. Justice Sotomayor writing, When a President uses his official powers in any way. Under the majority's reasoning, he will now be insulated from criminal prosecution. Orders the Navy's SEAL Team 6 to assassinate a political rival, immune. Organizes a military coup to hold on to power, immune. Takes a bribe in exchange for a pardon, immune. Even if these nightmare scenarios never play out, the damage has been done.

Laura Jarrett joins us now live outside the Supreme Court tonight. Laura, what are official or unofficial actions by the President? Will be decided by a lower court, and that's going to push the timeline for another Trump trial?

Yes, Tom. Judge Chuck now has a heavy burden to try to figure out what, if anything, remains in this indictment. It's going to take some time for her to even get the case, schedule a hearing, potentially bring in witnesses and evidence, all of which Mr. Trump may try to appeal. Tom?

Laura Jarrett leading us off tonight. Laura, thank you for that. Halley Jackson is following the politics of all this. Halley, former President Trump is already out there declaring victory after this ruling?

That's right, Tom, calling this a big win for the Constitution and democracy, in his words, saying it should end what he describes as the witch hunt against him. Now, this ruling virtually assures his trial will get pushed until after election day. And politically, for him, that is a win. But the White House, in a new statement, says nobody is above the law and that the country needs leaders like President Biden who, in their words, respect the justice system and don't tear it down. But his campaign already fundraising off this ruling, Tom.

Halley, I know you have some reporting on long-time Trump ally Steve Bannon heading to prison to start his four-month sentence?

That's right. The former White House senior adviser walking into that Connecticut prison telling reporters he is proud to serve time. You see it there. He was convicted on charges of contempt of Congress for defying a subpoena to testify before the January sixth committee. He's set to be released the week before election day.

Tom. All right, Halley, thank you for that. Thanks for watching. Stay updated about breaking news and top stories on the NBC News app or follow us on social media.
