28 U.S. Code § 1251 - Original jurisdiction

(a) The Supreme Court shall have original and exclusive jurisdiction of all controversies between two or more States.
(b) The Supreme Court shall have original but not exclusive jurisdiction of:
(1) All actions or proceedings to which ambassadors, other public ministers, consuls, or vice consuls of foreign states are parties;
(2) All controversies between the United States and a State;
(3) All actions or proceedings by a State against the citizens of another State or against aliens.

Look at b1. In the investigation of the Trump/Russian connection, the Russian ambassador and other Russian diplomatic characters are parties to the question. Now, if we just had a Justice Department with any integrity, we could bring a case to the SCOTUS, which has original jurisdiction in such matters.

Sadly, we do not have such a justice department, and the SCOTUS is tainted as well. But, it's a nice fantasy to consider.

1. I Think That Would Require Them to Be Formal Parties in the Controversy

not just witnesses or persons with evidence

2. The language is amply vague.

There appears to be evidence that they were, indeed, parties to actions that affected the 2016 elections and influenced the Republican Party Platform with regard to Russia.

But, we do not have an administration that would take any such action, so the question is moot, really.

3. It's not vague a all.

"Party" is a term of art. A party is a plaintiff, defendant, or third party defendant. It could also include an intervenor or a person or entity who settled in the appropriate circumstance.

The term party presupposes that a lawsuit has been initiated. Courts do not get involved in investigations. There isn't an active civil suit or criminal case pending, so that subsection of the judicial code is not applicable.
