A senior U.S. intelligence official-turned-whistleblower said Obama-era superiors pressured him to endorse flawed conclusions in a high-profile intelligence report on Russian election interference and that he was later cut out of key discussions after raising concerns about the Steele dossier’s role in shaping that assessment, according to newly declassified information.

The whistleblower, who served as deputy national intelligence officer at the National Intelligence Council from 2015 to 2020, said in a declassified statement published Thursday that he “could not concur in good conscience” with parts of the Jan. 6, 2017, intelligence community assessment, which concluded that Russia interfered in the 2016 election with the specific goal of helping elect President Donald Trump.
