Ukrainian President Volodymyr Zelenskyy will address the U.S. Congress on Wednesday morning.
In a letter to lawmakers, House Speaker Nancy Pelosi and Senate Majority Leader Chuck Schumer invited members of the House of Representatives and the Senate to attend the virtual event at 9 a.m. Eastern Daylight Time.
"The Congress remains unwavering in our commitment to support Ukraine as they face Putin's cruel and diabolical aggression," the letter states.
Last week, Congress passed a spending bill that would send $13.6 billion in aid to Ukraine. The money will go toward humanitarian assistance and the defense of the country.
Zelenskyy has repeatedly asked the U.S. to implement a no-fly zone over Ukraine.
However, President Joe Biden has refused, saying a no-fly zone could force the U.S. to directly engage with Russia and lead to a wider conflict.
