Michael Isikoff of Yahoo News recently reported that the Trump Administration sought to lift economic sanctions on Russia immediately after entering office, leading to an under-the-radar battle within the government. Needless to say, the Trump Administration has never been shy about their desire to build better relations with Russia. To date, however, the only public rationale to radically shift U.S. policy toward Russia is that Russia should be a key ally in the fight against ISIS.
The fact that both the U.S. and Russia are battling against extremist Islamic groups would seem to suggest that the notion has some merit. At the same time, there is strong resistance to the idea throughout the agencies of the Executive Branch and in Congress.
