An Intelligence Community Whistleblower Board

Rajesh De, a deputy assistant attorney general at the Justice Department's Office of Legal Policy, is testifying before the Senate Homeland Security and Governmental Affairs Federal Workforce Subcommittee, and is proposing an interesting solution to the challenge of balancing whistleblower protections and national security concerns. He's suggested creating an intelligence community whistleblower review board within the executive board that could review cases, order security clearances restored if they're revoked as a form of retaliation, and inform Congress if agencies don't comply. The last proposal seems intriguing--much in the same way proposals to urge Inspectors General to report on the actual state of agency action on their recommendations make a lot of sense. But I don't know if it makes sense to situate such a review board within the executive branch, where it could be pressured, obfuscated, abandoned, underfunded, etc. Thoughts?
