Inspector General Michael Horowitz first announced the Department of Justice investigation in March past year.
Inspector General Michael Horowitz's office found the Russian Federation investigation was launched in August 2016 based on suspicions shared with the US about former Trump campaign aide George Papadopoulos, and that the controversial "dossier" authored by former British spy Christopher Steele was not relied upon in opening the investigation.
The report also finds, however, that there were "significant inaccuracies and omissions" in the application to surveil former Trump campaign adviser Carter Page, a finding that was surfaced in the media in recent days.

The report found that some of the information the Federal Bureau of Investigation put in its warrant application for Page was based on reporting by Christopher Steele, a former British spy who authored a controversial so-called dossier accusing Trump of conspiring with the Russians. Earlier this year, Attorney General Bill Barr said "spying" did occur against the Trump campaign during the campaign. Lindsey Graham has said he expects the inspector general will personally make "recommendations as to how to make our judicial and investigative systems better".
"Because it's a disgusting thing that took place, and it should never happen to another president", he told reporters before leaving the White House for a fundraiser in Florida.
Next, Horowitz is scheduled to testify before the Senate Judiciary Committee Wednesday morning to answer questions about his probe.
In Tuesday's impeachment hearing in the House Judiciary committee, Republican Rep. Matt Gaetz suggested, without providing evidence, that Horowitz's report would be so damning that it would shift the focus of impeachment to former President Barack Obama. I've never spoken to him.

The move provides Durham powers that Horowitz lacked, such as convening a grand jury and issuing subpoenas for witnesses and documents.
That investigation has become a criminal probe, people familiar with the matter have said, though it is unclear what possible crimes are being examined.
A source familiar with the process said that Barr is not now expected to offer a formal response to the Horowitz report upon its transmission to Congress that the DOJ at times includes with IG reports critical of the department.
