But Mr. Gorkov said publicly that the meeting was business-related, and another witness told investigators that Mr. Gorkov was in New York to discuss “postelection issues with U.S. financial institutions.” At the time, Mr. Kushner’s family business was desperately seeking investors for its flagship property, a Manhattan skyscraper awash in debt.
Mr. Gorkov requested a second meeting, but an aide to Mr. Kushner told investigators that he did not respond because of federal investigators’ interest in contacts between Russians and people in Mr. Trump’s orbit.
Investigators also failed to get to the bottom of a June 2016 Moscow trip by Carter Page, a Trump campaign foreign policy adviser. Mr. Page sent an email to another campaign official saying that he had met with Arkady Dvorkovich, a Russian deputy prime minister, who had “expressed strong support for Mr. Trump.” But “Page’s activities in Russia — as described in his emails with the campaign — were not fully explained,” the report said.
Investigators focused heavily on the Trump campaign’s efforts to learn about WikiLeaks’ plans to release the emails that the Russians hacked from Mrs. Clinton’s campaign and the Democratic Party.
Mr. Gates, the former campaign deputy, told prosecutors that by late summer 2016, the Trump campaign had incorporated the possible release of hacked emails into its political strategy. En route to La Guardia Airport that summer, the report stated, “Candidate Trump told Gates that more releases of damaging information would be forthcoming.”
Although that paragraph is partly redacted, other accounts suggest that Mr. Trump had learned that from Roger J. Stone Jr., a former campaign adviser who was in contact with the Russian hackers. Mr. Stone is now awaiting trial on charges of lying about his efforts to reach Julian Assange, the founder of WikiLeaks, and trying to influence the congressional testimony of a witness with ties to Mr. Assange.
Even if it fell short of a crime, Mary McCord, who headed the Justice Department’s national security division from 2016 to 2017, said the Trump campaign’s willingness to profit from stolen documents was remarkable.
“There is no way you could come away from this report without recognizing that there was a high level of interest and encouragement by people associated with the campaign in Russia continuing with its interference activities, particularly in the release of emails,” she said.
