The Justice Department watchdog excoriated the FBI for relying upon British ex-spy Christopher Steele’s dossier in obtaining Foreign Intelligence Surveillance Act warrants to monitor onetime Trump campaign adviser Carter Page.

Inspector General Michael Horowitz, who released a report on Monday showing his findings regarding allegations of surveillance abuses, also found the FISA process was significantly flawed and marred by serious mistakes and missteps, but determined that the initiation of the Trump-Russia investigation itself crossed the low threshold to be properly predicated and was not influenced by political bias as some of President Trump’s allies have alleged.
