TAMPA, Fla. (AP) — Attorney General Jeff Sessions spoke about the nation’s opioid crisis during a visit to Florida on Wednesday, praising the response of President Donald Trump, federal agents and prosecutors to the crisis while acknowledging that prescription drug abuse has hit the state hard.

During his 25-minute remarks in Tampa at the U.S. Attorney’s Office, Sessions highlighted several overdose cases in Central Florida and said federal investigators continue to crack down on “darknet” marketplaces, a computer network used primarily for illegal file sharing where people sometimes buy illegal drugs.

He added that the Drug Enforcement Agency is now asking medical practitioners whether they have received continuing medical education on prescribing or dispensing opioids when they apply for a license or renew.
