BRIDGEWATER, N.J. – President Trump promised to win the fight against a U.S. epidemic of opioid drug use, but offered no new steps to do so and did not act on a recommendation made by a presidential commission that he declare a national emergency.

Trump spoke at an event he had billed as a “major briefing” on the opioid crisis during a two-week “working vacation” at his private golf club in New Jersey. He also used the appearance to unexpectedly issue a stern warning to North Korea over its threats to the United States.

The Republican president said the United States has no alternative but to stem spreading opioid use, but more than six months into his presidency announced no new policies to combat a public health crisis that kills more than 100 Americans daily.

“I’m confidant that by working with our healthcare and law enforcement experts we will fight this deadly epidemic and the United States will win,” Trump told reporters. “We’re also very, very tough on the southern border where much of this comes in, and we’re talking to China, where certain forms of man-made drug comes in, and it is bad.”

U.S. Health and Human Services Secretary Tom Price said the administration was still working to devise “a comprehensive strategy” to be presented to Trump “in the near future.”

A commission created by Trump to study opioid abuse urged him last week to declare a national emergency to address what it called an opioids crisis, framing its death toll in the context of the Sept. 11, 2001, attacks on the United States. An emergency declaration could free up federal resources for the effort.

“The resources that we need or the focus that we need to bring to bear to the opioid crisis at this point can be addressed without the declaration of an emergency, although all things are on the table for the president,” Price told a later news briefing.

According to the U.S. Centers for Disease Control and Prevention, opioids were involved in more than 33,000 U.S. deaths in 2015, the latest year for which data is available, and estimates show the death rate has continued rising.
