NABU leaked the existence of the ledgers on May 29, 2016. Later that summer, it told U.S. media the ledgers showed payments to Manafort, a revelation that forced him to resign from the campaign in August 2016. A Ukrainian court in December concluded NABU’s release of the ledger was an illegal attempt to influence the U.S. election. And a member of Ukraine’s parliament has released a recording of a NABU official saying the agency released the ledger to help Democratic nominee Hillary Clinton’s campaign.
