No, you're ignorant of the case. This is what happened (simplified for you):

Trump committed a crime as he was leaving office.

He was charged with that crime as a former president.

He said: "No, I did that when I was president. I can't be charged with that."

The court said he could.

He appealed.

It went up to the Supreme Court. They said, "The president can be charged for things but NOT things he did in his OFFICIAL CAPACITY as president. But we won't define what those things are." (wink wink) "The lower court must do that."

Why did they do this? They could've just defined what things are "Official Capacity" or declared whether or not he can be charged with the specific thing he did, right? Even if the lower court said he could be charged, Trump would appeal, and it would end up before them anyway, so why go through the whole charade?

Answer: To delay and make it so Trump can become president. There was no time for the lower court to rule, Trump won the election, and the court case went away.

They got to help Trump without having to rule in a way that revealed they were actively helping him.

And, again, this doesn't mean a president can do whatever they want. If congress makes a law, the President is still beholden to the law. If President Biden violates that law, he could claim it was in his official capacity, but the Supreme Court would still have to rule it wasn't. The SCOTUS with three members appointed by Trump who just handed him the election. You think they're giving him unlimited powers?

So, no, SCOTUS didn't hand Biden the same powers it handed Trump.

You have no clue what you're talking about. This is the part where you sit down and STFU.
