Senate Republicans handed President Donald Trump a victory in the administration’s fight against the fentanyl epidemic with the passage of legislation that imposes steep penalties on smugglers caught moving fentanyl analogs into or throughout the United States.

The Senate passed the Halt All Lethal Trafficking of Fentanyl Act 84-16 on Friday afternoon. Sens. Bill Cassidy (R-LA) and Martin Heinrich (D-NM) introduced the legislation to classify fentanyl-related substances as Schedule I permanently under the Controlled Substances Act, the highest possible rating.
