The dossier by itself was not what caused the warrants to be issued. Understand?
The dossier was the sole piece of evidence for the fisa warrants
Horowitz investigated that. Quote him saying that or you're lying....
FISA shocker: DOJ official warned Steele dossier was connected to Clinton, might be biased
When the annals of mistakes and abuses in the FBI’s Russia investigation are finally written, Bruce Ohr almost certainly will be the No. 1 witness, according to my sources.
The then-senior Department of Justice (DOJ) official briefed both senior FBI and DOJ officials in summer 2016 about Christopher Steele’s
Russia dossier, explicitly cautioning that the British intelligence operative’s work was opposition research connected to
Hillary Clinton’s campaign and might be biased.
Ohr’s briefings, in July and August 2016, included the deputy director of the FBI, a top lawyer for then-Attorney General Loretta Lynch and a Justice official who later would become the top deputy to special counsel
Robert Mueller.
At the time, Ohr was the
associate deputy attorney general. Yet his warnings about political bias were pointedly omitted weeks later from the Foreign Intelligence Surveillance Act (FISA) warrant that
the FBI obtained from a federal court, granting it permission to spy on whether the Trump campaign was colluding with Russia to hijack the 2016 presidential election.
