The Justice Department last year charged Russian oligarch Konstantin Malofeyev with violating sanctions imposed on Russia after its invasion of Ukraine, saying he provided financing for Russians promoting separatism in Crimea.

At that time, Garland said, he also announced "the seizure of millions of dollars from an account at a U.S. financial institution traceable to Malofeyev's sanctions violations."

In February, Garland said he authorized the transfer of that money for use in Ukraine.

"While this represents the United States' first transfer of forfeited Russian funds for the rebuilding of Ukraine," Garland said, "it will not be the last," he said in a statement.
