Trump phone calls add to lingering questions about Russian interference in 2016.

More than 200 pages into a sprawling, 1,000-page report on Russian election interference, the Senate Intelligence Committee made a startling conclusion endorsed by both Republicans and Democrats: Donald J. Trump knew of and discussed stolen Democratic emails at critical points late in his 2016 presidential campaign.

The Republican-led committee rejected Mr. Trump’s statement to prosecutors investigating Russia’s interference that he did not recall conversations with his longtime friend Roger J. Stone Jr. about the emails, which were later released by WikiLeaks.

Senators leveled a blunt assessment: “Despite Trump’s recollection, the committee assesses that Trump did, in fact, speak with Stone about WikiLeaks and with members of his campaign about Stone’s access to WikiLeaks on multiple occasions.”

The senators did not accuse Mr. Trump of lying in their report, released on Tuesday, the fifth and final volume from a three-year investigation that laid out extensive contacts between Trump advisers and Russians.
