The measure, which passed with bipartisan support and minor changes, now heads back to the House. It is just the second legislative victory for the new Republican-controlled Congress.

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 bill passed the Senate, 84 to 16, with all the no votes from Democrats. It next heads to the House, where a similar version has passed with significant Democratic support.
