Pentagon to tighten oversight of handling classified information in wake of leaks

A Pentagon review ordered in the wake of alleged classified leaks by a national guardsman found oversight policies have not kept up with the rapid increase in the number of people who have access to the nation's defense secrets. 

"As the department's population of cleared personnel and the number of facilities have grown over the past years, it has underscored the need to have a comprehensive and evolving security in-depth posture," a senior defense official told reporters Wednesday. 

Defense Secretary Lloyd Austin ordered the 45-day review into the Defense Department's security programs, policies and procedures after embarrassing leaks of classified information allegedly by 21-year-old Jack Teixeira started appearing in the news.
