Treasury Secretary Janet Yellen made a previously unannounced visit to Kyiv on Monday intended to highlight the U.S.' enduring support for the country days after the one-year anniversary of Russia's invasion.
Driving the news: Yellen is expected to hold "meetings and engagements" and announce the transfer of $1.25 billion in economic and budget assistance to Ukraine, according to a Treasury official, as continued U.S. economic support has grown as a divisive political issue.
