To make it crystal f**ing clear: him changing the policy of the US isn't treason. Cozying up to Russia or trying to reduce the size of the government are his prerogative as elected leader in a way that trying to change the result of an election is not. Ohh yeah and I forgot that he tried to get everyone to stop counting the votes while he was ahead! That also goes in the treason most foul bucket.

No, that function is within the purview of the legislature, not the executive branch.
