Wrong on so many counts my friend.
According to the Constitution:
Article III - :
section 1 - The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish. <- This is the part that created the Supreme Court
section 2, clause 1 - The judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution, the Laws of the United States, and Treaties made, or which shall be made <- This is the part that means they are the ultimate judges. Like all judges, what they rule on sets legal precedent, but because of section 1, there's no going higher than them. No court, no judge, no congress is above the Supreme Court, nor do they have "congressional power," whatever that means.
section3, clause 1 - Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort. <- Do you really think they're guilty of treason after reading this country's definition of treason?
