President Barack Obama is set to announce steps Tuesday to expand treatment for people addicted to heroin and prescription painkillers, the White House said.

Obama will travel to a summit in Atlanta to meet addicts in recovery, family members, medical professionals and law enforcement officials to talk about the opioid epidemic, which has become an issue in the 2016 presidential election campaign.

In 2014, a record number of Americans died from drug overdoses, with the highest rates seen in West Virginia, New Mexico, New Hampshire, Kentucky and Ohio.
