DES MOINES, Iowa - U.S. Health and Human Services Secretary Sylvia Mathews Burwell says the Obama administration will continue lobbying Congress for more money to help states fight the opioid epidemic.

Congress this week approved a bill that creates grants and other programs aimed at reducing the abuse of prescription pain relievers and heroin.

Burwell says President Obama will sign the bill but is disappointed it only provides a fraction of the $1.1 billion in funding he sought. She says the administration will press for additional money when Congress returns in September.

Burwell told governors that it's not clear how effective the bill will be without funding to deliver more medication-assisted treatment to addicts through state programs.
