The former head of the Ukrainian president’s office, Andriy Yermak, said he was “going to the front” in a cryptic message ob Friday after his shock resignation.

Yermak, widely considered the second most powerful man in Ukraine, went from the heights of his power to resigning in disgrace over the course of a few days, a major turnaround for the so-called “Green Cardinal.” On Friday evening, shortly after his resignation, the Ukrainian political heavyweight told the New York Post in a cryptic text message that he was headed for the front lines in the war with Russia.
