After missing a ride last year in the must-pass annual defense spending bill, a version of the bill that seeks to protect the genetic data of Americans while securing U.S. pharmaceutical supply chains made it into the 2026 National Defense Authorization Act, which is now just a Senate vote away from becoming law.
