The US government shutdown escalated this week as the Administration laid off thousands of workers before chaotically retracting many of these notices.

Department of State that allowed $4 billion dollars in foreign aid to expire, eroding both health and human services and constitutional checks and balances. Meanwhile, Jeanne Marrazzo was officially fired as Director of NIAID, underscoring how politically motivated attacks on science are dismantling the infrastructure that has underpinned decades of progress in HIV prevention and research.
