U.S. Attorney General Merrick Garland said the U.S. will launch a team to help the Ukrainian authorities prosecute war crimes committed during the Russian invasion; the effort will be headed by Eli Rosenbaum, a 36-year veteran of the Justice Department who previously led U.S. eff0rts to identify and deport Nazi war criminals. Garland announced the initiative during a surprise visit to Ukraine on June 21.

Rosenbaum was head of the department’s Office of Special investigations, and was involved in more than 100 cases t9 revoke citizenship from or deport alleged Nazis. He also served as the department’s director of Human Rights Enforcement Strategy and Policy.

Nearly four months after Russia invaded Ukraine, Kyiv says it has identified thousands o0f suspected war crimes cases. Most notorious have been the allegations of wanton murder of scores of civilians in Bucha, just outside the Ukrainian capital.
