There are some confusing reports about "US ban" on Russian rockets and/or engines and/or space cooperation more generally (ISS notwithstanding, as usual):
https://forum.nasaspaceflight.com/index.php?topic=52681.0ULA is mandated to stop using Russian engines, at least for government (only DoD or also NASA?) payloads. ULA is anyway moving entirely to Vulcan without Russian engines.
What's the situation with Antares? Can NG continue to purchase engines from Russia?

I believe they can keep using the Russian engines for commercial flights, just not military.
If I'm not mistaken the Russian engine ban was for "national security" payloads. So NASA and commercial clients can still use it.

The ban on Russian designed or made engines for national security payloads has been around for a while (2015 NDAA, with a relaxation in the 2017 NDAA).
The recent news coverage was because BIS published a new "Military End User" list of entities to be treated as part of the armed forces for export control purposes, which makes technical cooperation more difficult:
JSC Central Research Institute of Machine Building (JSC TsNIIMash);
JSC Rocket and Space Centre—Progress;
Mission Control — Moscow is part of TsNIIMash.
