The following press release is attributed to Pentagon Press Secretary Rear Admiral John Kirby:
The United States has offered its full support to the Russian government as it conducts security preparations for the Winter Olympics.
To that end, U.S. commanders in the region are conducting prudent planning and preparations should that support be required.
Air and naval assets, to include two Navy ships in the Black Sea, will be available if requested for all manner of contingencies in support of -- and in consultation with -- the Russian government.
There is no such requirement at this time.
