The money was originally allocated during the covid pandemic, but later authorized for additional services. They just can’t stand the idea of public money helping people when it could be used to tax cuts instead. Via the New York Times:

The Department of Health and Human Services has abruptly canceled more than $12 billion in federal grants to states that were being used for tracking infectious diseases, mental health services, addiction treatment and other urgent health issues.

The cuts are likely to further hamstring state health departments, which are already underfunded and struggling with competing demands from chronic diseases, resurgent infections like syphilis and emerging threats like bird flu.

State health departments began receiving notices on Monday evening that the funds, which were allocated during the Covid-19 pandemic, were being terminated, effective immediately.

“No additional activities can be conducted, and no additional costs may be incurred, as it relates to these funds,” the notices said.
