GOP Rep. Adam Kinzinger and a longtime aide to Speaker Paul D. Ryan each were given an early look at the final report added to the infamous “Steele dossier,” court documents in a lawsuit against BuzzFeed News show.

Christopher Steele, the former British intelligence agent who compiled the unsubstantiated research booklet in 2016 about Donald Trump’s connections to Russia before he became president, gave the report to Kinzinger and Jonathan Burks, Ryan’s longtime chief of staff, after he completed it on Dec. 13, 2016, according to the court memo.

In addition to Kinzinger and Burks, Steele also handed off the 17th and final report of his dossier, Report 166, to a longtime associate of Sen. John McCain and the top Russia expert on President Barack Obama’s National Security Council.

The judge in the BuzzFeed case, Ursula Ungaro, ruled in favor of the online publication on Wednesday. Russian businessman Aleksej Gubarev sued BuzzFeed for publishing its story without first investigating the dossier’s claim that Gubarev’s companies hacked Democratic computer systems ahead of the 2016 election. Gubarev has strongly denied the claim.

Among other potentially explosive claims, the dossier contains salacious, unsubstantiated reports of Trump having sex with prostitutes in Moscow, an encounter that it says might have been recorded on video by the Russian government.
