Both believed to have originated in Russia. Also on the agenda -- shared issues like arms control. We are not seeking conflict with Russia. We want a stable, predictable - relationship, but I've been clear -- the United States will respond in a robust and meaningful way when the Russian government engages in harmful activities.
