At the heart of the controversy over the Steele dossier is not just how reliable its contents were, but also what role it played in the FBI’s application for a Foreign Intelligence Surveillance Court (FISA) warrant against former Trump campaign aide Carter Page.
Republicans in Congress have long focused on the dossier, claiming that it formed the origins of what became Mueller's Russia investigation.
“On Carter Page and [former Trump campaign chairman] Paul Manafort, that information came from political opponents, the Clinton campaign fed right into the FBI, directed to the special counsel to go investigate what was in the infamous Steele dossier,” Nunes said.
Attorney General William Barr told lawmakers that he intends to review FBI and DOJ conduct during the formative days of the Russia investigation -- where the Steele dossier played a role.
Trump, meanwhile, has pledged to “get to the bottom” of the origins of the Russian probe, and has promised to “turn the tables” and investigate the investigators -- which could include closer scrutiny of the role that Steele's infamous dossier played.
