President Trump nominated Timothy Westlake to lead the Substance Abuse and Mental Health Services Administration (SAMHSA).

The details: Westlake is an emergency medicine physician and current SAMHSA chief of staff.

The bigger picture: The agency has operated without a permanent leader for over a year. Westlake would be taking over an agency the administration has upended. SAMHSA employees have praised Westlake.

What’s next: The Senate will schedule confirmation hearings for Westlake.

Meanwhile: Dr. Erica Schwartz, Trump’s nominee to lead the Centers for Disease Control and Prevention (CDC), appeared before the Senate Health, Education, Labor, and Pensions Committee last week for a confirmation hearing.
