Russia in general is not happy with us. The fracking that is providing lots of gas to the US has essentially killed imports. There were a a couple if HUGE lng terminals and fleets of ships set up to export to the US and now are being used to export to Europe undercutting the main income for Russia, fuel to Europe. That and their issues with existing pipelines having to pay taxes to other countries.
From a few reports I have read, their hard cash income has seriously gone down due to this and they are finding ways to retaliate.
