“We will continue to impose sanctions against Russia until it begins to maintain peace in the Donbass and stops the occupation of Crimea,” wrote Ortagus.

Today, we honored the lives of those who have perished as a result of Russian aggression in #Ukraine. We will continue to impose sanctions on Russia until it commits to peace in the Donbas and ends its occupation of Crimea. Our support is with Ukraine.
