The context: The letter came a day before Bhattacharya was set to testify before the Senate about Trump’s proposed budget.

Why it’s important: The administration has cut several NIH grants for studies focused on mental health and addiction, with some caught up in the political terminations referenced by the declaration. The budget proposes consolidating the institutes focused on mental health, drug use, and alcohol use, likely meaning less funding for these areas going forward.

What’s coming: Congress will have to pass a budget of its own for NIH.
