Maksim Chmerkovskiy, a professional dancer on Dancing With the Stars who grew up in Ukraine, documented his experience in Kyiv just as the invasion began. Though he has since returned to America, he plans to return to Europe to "join the efforts on the ground." Sean Penn, who is making a documentary about the ongoing conflict, recently spoke to Anderson Cooper and called for America to do more for Ukraine, for the sake of not just the people of the country, but democracy around the globe.
