At a separate event, Sen. Lindsey Graham, R-S.C., said he will be introducing a resolution supporting Ukraine’s case in international court claiming war crimes by Russia in its war against the Western-style democracy.

Graham said Russian President Vladimir Putin needs to know the world is watching and will hold him and his “cronies” accountable for the assault on Ukraine.

“Here’s what happens when you let a man get away with murder and theft and war crimes for twenty years. You can’t be surprised he keeps doing it. Enough. Stop it. End it,” Graham said Wednesday in a press conference at the U.S. Capitol.

A former military lawyer, Graham said he will be asking the Senate to vote on the resolution and call on U.S. allies around the world to join in supporting Ukraine’s case.

He was joined by Ukraine-born Rep. Victoria Spartz, R-Ind., who has spoken passionately about the U.S. role in saving her country.

“They now start killing civilians. You see what’s happened in the city of Kharkiv. They’re throwing using cluster ammunition and vacuum bombs,” Rep. Spartz said during the press conference.

“This city probably has majority of the population, actually Russian. They don’t care about the people. They don’t care if they’re Russian, or Ukrainian. They do not want to have free people. He cannot stand that somebody can stand up against a dictator and actually win,” she added.

The Biden administration wants Congress to provide $6.4 billion to pay for an initial U.S. response to Russia’s invasion of Ukraine, largely for military and humanitarian assistance in the region, three people familiar with the request said Friday.

Lawmakers are focusing on writing bipartisan legislation financing federal agencies for the rest of this year. Leaders hope to approve that roughly $1.5 trillion measure by March 11, when money temporarily financing government will run out.

It was initially unclear whether the Ukraine money would be part of that broader budget legislation, if not how quickly it would move and whether lawmakers would attempt to attach additional U.S. sanctions against Russia.

“I hope we can find consensus around a package to help Ukrainian people. But this to me is a lay up,” Sen. Graham said.

“This is maybe the most effective thing we can do is to let the generals in the army of Russia know you follow Putin’s orders at your own peril,” he added. “There were 161 people prosecuted in the Balkans conflict from privates to prime ministers, generals included. I want the world to rally around the rule of law.”
