Ukraine's president says his country is grateful for US support in the war so far, APA reports citing BBC.
Volodymyr Zelenskyy also credits US President Joe Biden's "personal involvement" in the provision of aid and assistance.
But he calls on Congress to do more and issue more sanctions "until the Russian military machine stops".
He suggests sanctioning all politicians in the Russian Federation.
"All American companies must leave the Russian market immediately because it is flooded with our blood," he adds, urging lawmakers to pile pressure on firms that remain.
