Ukraine's Zelenskyy tells Congress: 'We are united ... the entire free world'

In front of a roaring fire inside the Oval Office and flanked by reporters, Zelenskyy thanked President Biden for the support of the United States, which Biden said now includes a Patriot missile defense system and precision bomb kits.

"Thank you so much. Mr. President. Great honor for me to be here, with your journalists. Thank you so much for the invitation," Zelenskyy said. "I really wanted to come earlier, Mr. President knows, but I couldn't do it because the situation was so difficult."

Zelenskyy thanked Biden for his "big support and leadership," as well as the "ordinary" American people for standing with Ukraine.

"Thanks from our ordinary people to your ordinary people -- Americans -- I really appreciate." Zelenskyy said. "Thank you so much."

Welcoming Zelenskyy back to the Oval Office, Biden said it was an honor to be meeting again amid the "brutal" war being waged by Russia's Vladimir Putin.

"Hard to believe 300 days we've going through this, and Putin has waged a brutal assault on the Ukraine's right to exist as a nation and the attack on innocent Ukrainian people for no reason other than to intimidate," Biden said.

"And he's escalated his assault on civilians after hitting schools, orphanages, hospitals, landmarks, it's just -- and he's trying to use winter as a weapon. But the Ukrainian people continue to inspire the world. I mean that sincerely, not just inspire us but inspire the world with their courage and how they have chose resilience and resolve for their future," Biden said.

Biden said Democrats and Republicans will make sure Ukraine has the economic, humanitarian and security assistance they need to keep fighting and will "support Ukraine in pursuing a just peace."

"President Zelenskyy, the United States stands with the brave people of Ukraine, we stand with you, you've been a great leader," he said as he turned it over to Zelenskyy to give remarks.

President Biden and first lady Jill Biden greeted Zelenskyy on the South Lawn of the White House Wednesday afternoon just after 2 p.m. Zelenskyy, donning army green, shook hands with the Bidens after exiting the motorcade.

The South Portico, decorated with holiday wreaths, was also adorned with the American and Ukrainian flags.

"Mr. President, welcome back," Biden said.

In a show of support, Biden was wearing a blue-and-yellow striped tie, the colors of the Ukrainian flag.

President Zelenskyy has arrived at Blair House, which now has a Ukrainian flag flying overhead. Blair House, located across the street from the White House, is the residence where foreign dignitaries often stay when visiting Washington.
