According to the document, information from the the so-called Steele dossier was "essential" to the acquisition of surveillance warrants on Trump campaign aide Carter Page. It claims that then-deputy FBI director Andrew McCabe told the committee in December that without the information from the Steele dossier, no surveillance warrant for Page would have been sought.
The memo alleges that the political origins of the dossier — paid for by Hillary Clinton and the Democratic National Committee (DNC) — were not disclosed to the clandestine court that signed off on the warrant request.
The document claims that although the FBI had "clear evidence" that the author of the dossier, former British spy Christopher Steele, was biased against Trump, it did not convey that to the surveillance court when making its warrant applications. Steele told then-associate deputy attorney general Bruce Ohr that he was "desperate that Donald Trump not get elected and was passionate about him not being president," the memo says.
