DOJ internal watchdog launches probe of Carter Page surveillance

Republicans have accused the FBI of "abuses" in spying on Trump associate.

While Horowitz's statement does not mention Page by name, sources have confirmed the inspector general's probe is tied to Page, a New York-based business consultant who volunteered for the Trump campaign.

For months, Republicans have complained that the court-approved surveillance of Page was based on "fake" information laid out in the controversial "dossier” authored by former British spy Chris Steele. The dossier alleged ties between Trump, his aides, and Russian operatives.

Page has denied any wrongdoing.

As part of its new investigation, "the OIG also will review information that was known to the DOJ and the FBI at the time the applications were filed from or about an alleged FBI confidential source," Horowitz said in his statement Wednesday. "Additionally, the OIG will review the DOJ's and FBI's relationship and communications with the alleged source as they relate to the FISC applications."

The issue came to a head earlier this year when Republicans and Democrats on the House Intelligence Committee released dueling memoranda about the circumstances behind the surveillance of Page.

Republicans claimed their memo illustrated "abuses" at the FBI and Justice Department, but Democrats insisted such claims were unfair and based on limited information.
