This person said Manafort would answer questions about the June 9, 2016, meeting, which was precipitated by the attorney, Natalia Veselnitskaya, offering to help Donald Trump’s campaign by providing dirt on Clinton. Manafort, who was Trump’s campaign chairman at the time, will also provide contemporaneous notes of the session, this person said.

Manafort attended the entire meeting and was one of three senior campaign officials there, along with Donald Trump’s son Donald Trump Jr. and son-in-law Jared Kushner, who left in the middle of the meeting.
