WASHINGTON —

Vice President Kamala Harris will travel to Poland and Romania next week, the White House says, as the Biden administration continues to show support for Ukraine and the U.S.' eastern NATO allies while Russia's invasion of Ukraine enters a dangerous new phase.

Harris' trip will take place from Wednesday through March 11, and will include stops in Warsaw and Bucharest, according to a Friday announcement by the White House. She'll meet with the leaders of both countries to coordinate on their response to Russia's invasion and discuss how the U.S. can further support Ukraine's neighboring nations as they prepare to welcome Ukrainian refugees fleeing the conflict.

The White House says the leaders will also "discuss their continuing support for the people of Ukraine through security, economic, and humanitarian assistance and our determination to impose severe economic consequences on Russia and those complicit in Russia's invasion."

"Her visit will demonstrate the strength and unity of the NATO Alliance and U.S. support for NATO's eastern flank allies in the face of Russian aggression. It will also highlight our collective efforts to support the people of Ukraine," the White House announcement states.

The Eastern Europe visit will take place on the heels of Harris' latest international travel to the Munich Security Conference, where she met with U.S. allies and partners including Ukraine's President Volodymyr Zelensky. Harris also spoke over the phone with several Eastern European leaders on Tuesday, including Polish Prime Minister Mateusz Morawiecki and Romanian Prime Minister Nicolae Ciuca.

The Hill was first to report on the discussions to send Harris to Poland and Romania.

U.S. and other Western officials warned this week that Russia's strategy is shifting toward a "slow annihilation" of the Ukrainian military, warning that Russia could focus on violent bombardment of cities and civilian targets as the conflict becomes a grinding war of attrition.

Since Russia invaded Ukraine last week, the U.S. and allies have ramped up their responses to the conflict, establishing a variety of economic sanctions and providing Ukraine aid.

Since the invasion began, Russia's military has launched more than 500 missiles, a senior US defense official said Friday.

A White House statement following Tuesday's calls said that in each of her conversations, "the Vice President underscored the strength and unity of our Alliance and welcomed each of her counterparts' leadership and coordination on robust response measures, including sanctions and other economic measures through the European Union. They also discussed the robust NATO response."

Harris also reiterated the U.S.' support for Ukraine and "reaffirmed U.S. support for the international rules and norms that have brought peace and security in Europe since World War II and that have served as the foundation of the NATO Alliance."

Amid heightened tensions between Ukraine and Russia, lawmakers are looking at the potential implications of the next moves. 

The Pentagon announced it planned to send forces to Poland, Romania and Germany to bolster NATO's eastern flank, while more forces remain on standby. 

The U.S. Helsinki Commission, a commission independent of the federal government, met Wednesday to discuss the developing situation and hear insight into the implications beyond Ukraine and what messages potential U.S. actions send. 

"The Kremlin's threat menaces not only Ukraine, our partners in Georgia, and the wider region but also the long-cherished dream and long-standing bipartisan U.S. policy to work towards a Europe whole and free," said Sen. Ben Cardin, the commission's chairman. 

It comes as Congress debates sanctions on Russia. Ukraine's foreign minister said it's preparing for all possible scenarios, but that active diplomacy works. 

"It puts a lot of pressure on us but it is still insufficient for a large-scale military operation against Ukraine," said Dmytro Kuleba in a video released by the Ukranian Foreign Ministry. 

During the commission hearing, lawmakers heard expert testimony into Ukraine and Russia from high-profile witnesses. Experts told lawmakers unity seen surrounding the conflict may have surprised Putin. 

Former ambassador to Ukraine William Taylor explained it can't be assumed Putin’s bluffing since he’s invaded before, but that he’s looking at unity and the possibility of severe sanctions. Taylor said actions have appeared to deter an invasion for now, but reiterated strong steps until Putin withdraws military force.

Former U.S. National Security Council official Fiona Hill told lawmakers Russia may feel emboldened by developments in Eurasia, and look at the U.S.' role in addressing upheavals.

 

"We should continue to make clear to Moscow we are open to negotiation as Chairman Cardin has said … but not under the current coercive circumstances," said Hill. "We need to reframe this crisis for what it is as the administration has just done in the United Nations. This Is not a proxy conflict, this is not aggression by the United States or NATO, this is not a righteous effort to counter some great historic wrong as President Putin says. This is an act of post-colonial revisionism."

On the Hill, the move to send troops to Europe drew praise, as well as a split reaction between high-profile Republicans. 

Senator Lindsey Graham said he completely supports the decision, while Senator Josh Hawley called it a mistake, pushing for a focus on China instead. Senator Mitch McConnell praised it, but also called for more assistance to Ukraine and sanctions now. 

"Yesterday, I was glad to hear that U.S. forces are finally moving to reinforce our Eastern Flank allies. I urged President Biden to take this step nearly two months ago. I hope this belated action will lead other NATO allies to follow suit," McConnell said.
