Vought is breaking the law but he is not “going rogue.” At his confirmation hearings, Vought told Republicans he would do this and they voted for him anyway. If they want to stop him, they still can via impeachment. They won’t.
Congress funded the CDC's Alzheimer's work, the sickle cell and epilepsy data programs and a rape prevention unit, and Vought simply will not release the money. Grassley told him to his face he lacks the authority. The pocket rescission alone took 4.9 billion.
