Trump Nominates Emergency Doctor Timothy Westlake to Lead SAMHSA Amid Policy Shifts

President Donald Trump has officially nominated Dr. Timothy Westlake, a Wisconsin emergency physician and the current Chief of Staff at the Substance Abuse and Mental Health Services Administration (SAMHSA), to lead the crucial federal agency as Assistant Secretary for Mental Health and Substance Use. This move, announced on July 14, 2026, positions a doctor with extensive frontline experience in addiction and a personal history of recovery at the helm of an agency central to the nation's behavioral health efforts, pending Senate confirmation. The nomination comes as SAMHSA has faced periods without a Senate-confirmed leader, following the departure of Dr. Miriam E. Delphin-Rittmon in early 2025. Westlake's track record includes championing class-wide fentanyl scheduling, an approach that became federal law through the HALT Fentanyl Act in 2025, and shaping prescription opioid reforms in Wisconsin. The Trump administration has recently rolled out several related policy initiatives, including efforts to curb psychiatric overprescribing and a National Drug Control Strategy that, while emphasizing border control, has seen friction with SAMHSA guidance on harm reduction services like fentanyl test strips. With Westlake's confirmation hearing yet to be scheduled by the Senate, the behavioral health community will be closely watching his potential leadership, especially concerning the future direction of addiction treatment, mental health service access, and the ongoing debate around harm reduction strategies. His appointment could signal a renewed focus on direct clinical experience and a more aggressive stance on the fentanyl crisis, aligning with the administration's broader public health and drug control agenda. Meanwhile, SAMHSA itself briefly faced a $2 billion grant termination scare in January 2026, which was quickly reinstated after bipartisan outcry, underscoring the agency's critical and sometimes contentious role.
