NEW YORK (AP) — Dr. Anthony Fauci is sitting before Congress, Robert F. Kennedy Jr. is on TV debating COVID lockdowns and Americans can’t agree on what science to trust. Political scientists and historians say the focus on COVID grievances half a decade after the virus’ peak demonstrates how some wounds it opened have never been closed. “The response to COVID has become a touchstone for Trump’s Republican Party,” Dallek said. While Trump has long expressed pride in his first-term Operation Warp Speed effort to disseminate COVID-19 vaccines quickly, saving millions of lives, his second administration’s approach to the vaccines has taken a different tone. Under Kennedy’s leadership, U.S. regulators have limited the availability of COVID-19 vaccines for Americans.
