The case for the Russian agent:
Example 1: Allowed Russian hacking, told the Ukraine to stand down on Crimea while giving Russia all the reasons they needed to annex Crimea, refused bi-partisan calls to send lethal aid to the Ukraine, refused bi partisan calls for additional sanctions on Russia, gave Russians bombing coordinates for "our guys" in Syria, decreased U.S. defense spending, attempted to slow roll NATO GDP/Defense mandate
Example 2: Sent lethal aid to the Ukraine, increased sanctions on Russia to the great financial detriment of Russian Oligarchs, expelled Russian diplomats, increased U.S. defense spending, hammering NATO "partners" to increase defense spending substantially-beyond 2% GDP threshold.
