Article III, Section 3. The definition 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.”
Calling for civil war and aiding an authoritarian country such as Russia, which is well known for being a long-time enemy and wants nothing more than the fall and decadence of the US, raises the question: if what Trump is doing is not treason, according to the Constitution, then I don’t know what is.
