The United States still has not seen a large-scale Russian reinforcement of its troops in Ukraine, even as it moves ahead with a mobilization, a U.S. military official said on Monday.
"Broadly speaking, we've seen relatively small numbers (of Russian reinforcements) ... but nothing large-scale at this stage of the game," the official said, speaking to reporters on condition of anonymity.
