On November 22, 2019, The Washington Post reported that a forthcoming United States Department of Justice Office of the Inspector General report found the origin of the FBI investigation was properly predicated on a legal and factual basis, and the report did not support several conservative conspiracy theories about the origin. On December 9, 2019, US Inspector General Michael E. Horowitz testified to Congress that the FBI showed no political bias at the initiation of the investigation into Trump and possible connections with Russia; In a Senate hearing on December 11, 2019, he stated that he "could not rule out political bias as a possible motivation for the 17 errors the FBI made in applications for the Carter Page surveillance." In a subsequent analysis of 25 unrelated FISA warrant requests, Horowitz found a pattern of similar errors that suggested systemic sloppiness by the FBI, rather than an effort to single-out Page.
