EWING - Gov. Chris Christie defended an internal investigation by his own lawyers into the Bridge-Gate scandal during Wednesday night's "Ask the Governor" radio show on NJ 101.5.

Critics say the report is incomplete because former aides and other key players were not questioned about the closures. 

Christie says there's a lot more to his investigation than the unnecessary interviews.

"Bridget Kelly, Bill Stepien, Bill Baroni, Dave Wildstein, Dawn Zimmer, Mayor Sokolich, all refused to be interviewed," Christie says. "Requests were made to all of them, but they all refused to be interviewed. You don't just come to conclusions from interviews. There's lots of documents that involve all those people which have been part of the public record and will be becoming part of the public record as we go forward."

The review will be officially released into public record Thursday morning.
