U.S. President Joe Biden assured that the United States will continue to provide assistance to Ukraine and called on Republicans in Congress to keep their word on assistance amid Russian aggression.

"I hope my friends on the other side [of political views] keep their word about support for Ukraine. They said they were going to support Ukraine in a separate vote. We cannot under any circumstance allow America’s support for Ukraine to be interrupted. I fully expect the Speaker [of the House of Representatives] to keep his commitment for the secure passage and support needed to help Ukraine as they defend themselves against aggression and brutality," Biden said at briefing at the White House on Sunday.

He said among Republicans and Democrats, both in the House of Representatives and in the Senate, the overwhelming majority of legislators support Ukraine.

"Get this done [help for Ukraine]. Stop playing games," Biden said.

He also appealed to the Ukrainians with confidence in continued support from the United States.

"I want to assure our American allies and the American people and the people of Ukraine that you can count on our support," Biden said.
