Lewandowski said Saturday on "Fox & Friends" that the FBI and Department of Justice (DOJ) "probably did not follow proper procedure" in procuring a surveillance warrant for former Trump campaign adviser Carter Paige as part of the federal Russia probe.

"If that is the case, then there is no question that an additional special counsel should be put in place to review this process and hold people accountable. This is absolutely imperative," Lewandowski said of alleged Foreign Intelligence Surveillance Act (FISA) abuse.

"Our Office of Inspector General has almost 500 employees, investigators and prosecutors, and they're going to work on this and get to the bottom of it," Sessions told Fox News's Tucker Carlson.

When pressed on whether a special prosecutor should carry out the investigation instead of the DOJ inspector general, Sessions said that "it could be one day that a special prosecutor would be required."

"I think the [inspector general] report needs to come out sooner rather than later," Lewandowski responded Saturday on Fox News, arguing that Sessions needs to "move faster."

"What are we waiting for? Let's get this started right away," he said.
