ANDREW KRAMER, The New York Times:

Those are all very good questions.

Thank you.

The ledger is called in Ukraine the black ledger, and it's a collection of papers, perhaps 400 pages, as you mentioned, with handwritten notes describing payments from the Party of Regions, which is a pro-Russian political party that Paul Manafort worked for before becoming manager of the Republican campaign this year in the United States.

The outlays described in this ledger included legitimate campaign expenses, such as advertising, travel for candidates, and also illegal activities under any definition, such as payments to the electoral commission of Ukraine, members of the electoral commission receiving money from this same fund.

According to the ledger, there is also mention of Paul Manafort. So, at the same time, you have a payment for a campaign consultant, there are outlays to potentially illegal activities like bribing.

Where the money came from, also a very good question. I spoke with a senior member of the Party of Regions who described using the system before he left the party. And he said that the money was, in part, undocumented campaign contributions to the Party of Regions and also money extorted from business owners in Ukraine by the party.
