U.S. Under Secretary of State for Political Affairs Victoria Nuland arrived in Kyiv on Jan. 31, said U.S. Ambassador to Ukraine Bridget Brink.
"Today we will meet government leaders, veterans, and civil society to underscore our shared commitment to defeating Russian aggression in Ukraine," Brink wrote on the social media platform X.
Earlier this week, Brink welcomed three U.S. inspectors who arrived in Kyiv to oversee American aid.
Nuland has had a long history of working in Ukraine, becoming the U.S.'s point person in Kyiv following the 2014 EuroMaidan Revolution and the subsequent beginning of Russia's war on Ukraine.
Nuland is often credited with helping spearhead the effort for the U.S. to increase its provision of aid and non-lethal assistance to Ukraine.
