MOSCOW (Reuters) -Daniel Martindale, a U.S. citizen who helped the Kremlin target Ukrainian troops and was then spirited out of eastern Ukraine by Russian special forces, has received a Russian passport in Moscow. Russian state television broadcast a report on Tuesday showing Martindale, with a trim beard and dressed in a suit and tie, smiling as he received his new documents. "I, Daniel Richard Martindale, voluntarily and consciously, accepting the citizenship of the Russian Federation, swear to observe the constitution," he said in Russian.
