NASA Associate Administrator Michael O’Brien outlined the agency’s position in a memo to employees: “This suspension includes NASA travel to Russia and visits by Russian government representatives to NASA facilities, bilateral meetings, email, and teleconferences or video conferences.

Last week Russian cosmonauts Alexander Skvortsov and Oleg Artemyev flew to space with NASA astronaut Steve Swanson on board a Russian Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan.
The Russians are the only nation with a launcher that can ferry human passengers to the ISS.
The decision will provoke a great deal of discussion of NASA’s ongoing work to bring human spaceflight capability back to the US by the end of the decade.
