The White House has announced President Trump will nominate Pennsylvania Congressman Tom Marino to lead the Office of National Drug Control Policy (ONDCP), according to The Washington Post.

In April, CBS News reported that Marino was expected to be named the next head of ONCDP. In May, Marino withdrew from the position, citing a critical illness in his family.

Marino has worked to expand access to opioid addiction treatment. He was appointed to serve on the House’s committee combating the opioid epidemic in 2016, after two bills he introduced on drug control were enacted.

One of the bills, the Transnational Drug Trafficking Act, aims to curb drug trafficking across borders. The other bill increases collaboration between prescription drug distributors and the Drug Enforcement Administration to combat drug use.
