One day after slashing hundreds of millions in federal grants that supported mental health and addiction care, the Trump administration is backtracking and plans to restore the funds, according to two officials with knowledge of the decision. The reversal came after intense backlash to the nearly $2 billion in cuts by the Substance Abuse and Mental Health Services Administration, or SAMHSA, which sent termination letters to hundreds of nonprofits on Tuesday night. The letters said their grants had been cut because their programs "no longer effectuate" the agency's priorities but did not explain how, according to recipients.
