For more than a year and a half, Inspector General Michael Horowitz has been investigating alleged misconduct related to the FISA warrants delivered by the Foreign Intelligence Surveillance Court (FISC). The Justice Department and FBI obtained warrants in 2016 to surveil Trump adviser Carter Page. It is unclear, at this point, if Page was the only Trump official that the DOJ obtained a FISA warrant against.

That highly anticipated report will likely spark new congressional investigations and deliver critical information to other federal reviews probing allegations of abuse by the Justice Department and the FBI.

“As soon as Horowitz is done with his review of the FISA warrant application, the counterintelligence investigation, the Trump campaign, we’ll have a hearing in public with Horowitz and we’ll call a bunch of witnesses,” Senate Judiciary Committee Chairman Lindsey Graham, R-S.C., said on Fox Business’ “Sunday Morning Futures.”

Last month, Horowitz submitted a draft of his report to Attorney General Bill Barr, who was reviewing the document -- fueling the belief that the public release was coming soon.

But a Justice Department official told Fox News last week that the report is still in the declassification process — one of the final steps to be completed before the report is released to the public.

Horowitz has been probing how the infamous and salacious anti-Trump dossier compiled by former British spy Christopher Steele was used to secure the original FISA warrant for Page in October 2016, as well as three renewals.

Horowitz also has looked into why the FBI may have regarded Steele – funded by the Hillary Clinton campaign through law firm Perkins Coie – a credible source, and why the bureau used news reports to bolster Steele’s credibility before the FISA court.

President Trump -- who has the authority to declassify and release as much of the report as he wants -- has been hyping its forthcoming release. “The IG report is going to come out soon, and we’ll see what happens," the president told reporters last week, adding he's "waiting for the report like everybody else.”

“But I predict you will see things that you don’t even believe, the level of corruption — whether it’s [James] Comey; whether it’s [Peter] Strzok and his lover [Lisa] Page; whether it’s so many other people — [Andrew] McCabe; whether it’s President Obama himself,” Trump charged.
