Members of Congress Wednesday said they were deeply moved by Ukrainian President Volodymyr Zelenskyy's address to U.S. lawmakers, including a graphic video he presented showing the horrors of Russia's war on his country.

"It was heart-wrenching," Sen. Raphael Warnock, D-Ga., said of the video. "It underscored the human side of this tragedy. These are families, children, and lives disrupted in a way that's really unspeakable."

"You could see more concern in his eyes this time than what we saw a week or so ago when we did a Zoom with him," Sen. Tommy Tuberville, R-Ala., told Fox News Digital.

"The video really captured the moment – devastating. Hopefully people, not only our country gets to see that video, which is very graphic. The whole world needs to see it," Tuberville added. "That's the trouble we're in with these dictators trying to do what they're doing."

"It is a gut punch and reminder of how we have to help the Ukrainian people in this moment," Assistant House Speaker Katherine Clark, D-Mass., told Fox News Digital. 

"To see the images of the beauty of Ukraine before all of this started and then show images of what these bombed out buildings look like, children with blood all over them, dead bodies in the street, putting people who had been murdered into mass graves – incredibly, incredibly moving," Rep. Cheri Bustos, D-Ill., said.

Zelenskyy's speech comes at a critical juncture in the war as Russian forces continue to bombard Ukraine's infrastructure and kill civilians, and encircle its capital of Kyiv. Zelenskyy also is the target of assassination plots by Russian saboteurs in Kyiv, he said.

In the address, Zelenskyy appealed to Americans emotions, invoking events including 9/11, Pearl Harbor, and Dr. Martin Luther King Jr.'s "I Have a Dream" speech. He asked the U.S. to enforce a no-fly zone over Ukraine – a proposal lawmakers say is a nonstarter due to the risk of confrontation with Russia – or alternatively to provide Ukraine with fighter jets and anti-aircraft weapons. 

Zelenskyy also asked for President Biden directly in his speech.

"I'm addressing the President Biden," Zelenskyy said. "You, the leader of your nation, I wish you to be the leader of the world."

Members of Congress effusively praised Zelenskyy and his speech – even if its potential policy implications were not immediately clear.

"He is obviously a leader that is hurting for his country, cares deeply, a courageous man," Rep. Louie Gohmert, R-Texas, said. "The video that he showed along with his speech was deeply touching... He's up against an evil leader of Russia."

"I admire him," Sen. Rick Scott, R-Fla., who appeared to have been crying, said of Zelenskyy's speech. "My heart goes out to what's going on. My heart goes out to what's going on. I wish our president would move. We need to get the planes there. We need to get more anti-aircraft equipment there. We need to get more support."

Sen. Mark Kelly, D-Ariz., called the scenes in the video "tragic," adding, "Vladimir Putin is now attacking civilians, which is clearly a war crime."

"You looked at those children and senior citizens and, it's murder, there's no other way to describe it," Sen. Ron Wyden, R-Ore., said.

"It was a very powerful speech and a very vivid reminder of how Putin's war is raining down on children, old people, everyone in Ukraine," Sen. Elizabeth Warren, D-Mass., said. "President Zelenskyy used that video to make very clear what it's like on the ground in Ukraine."
