In the interview at the immigration center on Monday, Ms. Vashukevich said that she had often recorded conversations between Mr. Deripaska and his associates, and that she had 16 to 18 hours of recordings, including conversations about the United States presidential election.
“They were discussing elections,” she said. “Deripaska had a plan about elections.”
But, she added, “I can’t tell you everything.”
Some of the conversations were with three people who spoke English fluently and who she thought were Americans, she said.
