The Trump administration’s effort to cut back on federal funding for the National Institute of Health for research programs at universities and medical systems has been blocked nationwide.

Agencies continue to suspend funding, despite multiple court orders blocking the federal freeze. Experts say the Trump administration’s actions set the stage for challenges to Congress’ authority — and the limits of the presidency.

Sen. Susan Collins (R-Maine) slammed the National Institutes of Health’s decision to slash billions of dollars in “indirect” costs for biomedical research funding, calling the move mandated by the Trump administration “devastating” and a “poorly conceived directive.”
