"Lawmakers Hit Back at DoD Proposal Limiting Information-Sharing with Congress" https://www.military.com/daily-news/2019/05/22/lawmakers-hit-back-dod-proposal-limiting-information-sharing-congress.html

• "This policy … accuses Congress of being a security risk for classified information, which is both inexcusable and inaccurate," Smith and Thornberry said in a joint statement Wednesday. "The department is not in a position to evaluate defense committees' worthiness to receive classified information, nor characterize our ability to appropriately protect it."

Unlikely that DoD had not conducted an evidence-based security review of DoD security requirements & determined with confidence that Congress rates low per DoD's security threshold.

Why no obvious questions from the media?

To the best of my understanding DoD leadership have 3 major responsibilities: 1) accomplish given objectives, b) ensure security of personnel, c) ensure security of equipment. All the more difficult to successfully accomplish if or when people outside the DoD chain (for instance, Congress) play loose and fast with sensitive information.
