WASHINGTON (Reuters) - A U.S. judge ordered accused Russian agent Maria Butina jailed on Wednesday pending trial after federal prosecutors warned that she has ties to Russian intelligence and was a flight risk.

During a hearing in U.S. District Court for the District of Columbia, prosecutors showed a photo of Butina meeting an alleged Russian intelligence operative at a Washington restaurant.
