Health and Human Services Secretary Robert F. Kennedy Jr. and his Make America Healthy Again (MAHA) allies are hailing Stephen Miller's rise to White House chief of staff as a reset for a frustrated movement. On Friday, Kennedy wrote on X that, after himself, Miller was the administration's strongest MAHA supporter. He added, "It's time to unleash the Kraken." The post came the same day President Trump announced that Miller, his deputy chief of staff, would replace Chief of Staff Susie Wiles starting Monday.
