Article III, Section 3, Paragraph 1, of the Constitution of the United States:
"Treason against the United States, shall consist only in levying War against them,
or, in adhering to their Enemies, giving them aid and comfort."

The "aid and comfort" prong of treason has been interpreted
by SCOTUS as requiring proof of four elements:
1. an intent to betray the United States (which can be inferred from);
2. an overt act;
3. witnessed by two people; and
4. that provides aid and comfort to an enemy of the United States.

IMHO, this car has rolled off of the bridge.

1. an intent to betray the United States (which can be inferred from); 2. an overt act; 3. witnessed by two people; and 4. that provides aid and comfort to an enemy of the United States.

Those are the Constitutional requirements, no "interpretation" required.

No person shall be convicted of Treason unless on the Testimony of two Witnesses to teh same overt Act, or on Confession in open Court

That quote is the sentence after the one you quoted.
