> Trump is in this for himself. If he appears to represent Russian interests that's likely because he has made some kind of deal with Putin that benefits him personally.

That's usually how one state usually acheives a compromise of another state’s government, by finding the right weak links and making deals with them (the chief of state and/or head of government, and especially the person holding an office which serves simultaneously as both, is pretty much the ideal case for this, though in practice it is often only people a few steps down.)

So, while that description is true, it supports and explains rather than contradicts the claim that Russia has compromised the US government.
