Health and Human Services Secretary Robert F. Kennedy Jr. is drawing bipartisan praise for a lesser-known policy push: ending animal testing in medical research. The effort, overshadowed by his vaccine skepticism, has sparked legislative action on Capitol Hill.

Multiple lawmakers have introduced bills to reduce or eliminate federally funded animal experiments, citing both ethical concerns and scientific advances. Kennedy’s position has earned him unusual acclaim from both animal rights groups and some medical researchers.

“One of his quieter pushes — ending animal testing in medical research — has earned him accolades,” according to Roll Call. The broad support for curbing animal testing reflects a rare moment of cross-party agreement in a divided Congress.

Animal rights organizations have praised the HHS secretary’s stance, while some biotech firms warn of slower drug development. The debate now shifts to funding for alternative testing methods, such as cell-based models and organ-on-a-chip technology.

Critics argue the shift could delay critical treatments, especially for rare diseases where animal models are the only option. The outcome remains uncertain as committees begin markup sessions.
