Pentagon officials on Friday confirmed the report to Fox News based on the latest intelligence available to U.S. officials. An estimated 20,000 Russian troops are now in Crimea, including roughly 15,000 that were stationed at its naval base in Sevastapol, Ukraine. A senior U.S. official told Fox News that no additional U.S. military commitments are expected as of Friday, adding that it's not in "national interest" to go war over Ukraine.
