During his first trip to the United States since taking office, Ukraine’s new prime minister Volodomyr Groysman appeared—as his rabbi described him—as “a man of action who doesn’t talk too much but gets a lot done.” Groysman, 38, was elected in April after months of government infighting and festering corruption under previous prime minister Arseniy Yatsenyuk.

Upon his election, Ukraine’s youngest-ever prime minister vowed to take on populism, corruption, and bad governance. While some were hopeful Groysman would bring Ukraine closer to the EU and unite conflicting government factions, others feared that his alliance with President Petro Poroshenko would mean more of the same: politicians propping up oligarchs.
