No, that is not what they ruled. What they ruled is a prosecutor needs to make the case whether it is an official act or not. Roberts said:
"The President is not above the law. But Congress may not criminalize the President’s conduct in carrying out the responsibilities of the Executive Branch under the Constitution.
It makes sense because any official act needs to have immunity so the president can act and opposition presidents can't prosecute them for an official act. This protects all presidents such as Obama cannot be prosecuted for his drone program. I am still reading it but this is what I understand so far.
I don't know if you recall, but let’s take a real example. In December of 2020, Trump had a conversation with his acting Attorney General Richard Donaghue and his acting Deputy Attorney General. He told them to just say that the election was corrupt, and “let me and the GOP Congressmen take care of the rest.”
This is after Bill Barr, his AG, had left the department. You recall, perhaps, that Barr, on December 7, 2020, told the Associated Press that there was not enough fraud to change the outcome of the election. And just weeks later, Trump is trying to pressure his own Justice Department to ignore those facts and work around the law.
Work around the law!
And because this was the President, speaking to members of his cabinet, by this ruling he would immune. The President, ordering his own government to break the law – and he’s immune.
That is what it is going to look like in real life.
I assure you, this is not what the Founding Fathers had in mind.
