How Trump Is Dismantling America’s Scientific Research Machine

The warning, buried in an obscure government report this summer, was unflinching.

The Defense Department’s vaunted network of research laboratories — whose scientists helped develop satellite communication, radar technology, and even the computer mouse — was in trouble.

The labs lost a significant share of their staff last year, largely in response to the Trump administration’s efforts to thin the federal work force, the report found. Refilling critical positions was proving difficult due in part to President Trump’s demand that new hires be screened for their loyalty to his goals. The report, issued by the Pentagon, pointed to “potentially grave consequences for the future of national defense.”
