 This is the first visit by Viktor Orban since Russia's full-scale invasion in February 2022 and comes the day after the Hungarian prime minister took over the European Union's rotating presidency. Mr. Orban, the European leader seen as closest to Vladimir Putin's Russia, has frequently criticized support for Ukraine. Earlier this year, it took weeks for other EU leaders to overcome Mr. Orban's opposition and gain approval for a 50 billion euro aid package for the country.
