President Donald Trump speaks to supporters and local politicians at an event in Manchester, N.H., Monday.

WASHINGTON — President Trump spoke Monday of using federal prosecutors to pursue “major litigation” against drug manufacturers alleged to have played a role in creating a nationwide epidemic of opioid abuse.

Speaking in New Hampshire at the White House’s rollout of a national opioids strategy, the president expanded upon a Department of Justice release last month in which Attorney General Jeff Sessions pledged to “hold accountable those whose illegality has cost us billions of taxpayer dollars.”
