Sen. Joe Manchin, D-W.Va., introduced legislation to restore enforcement power to the Drug Enforcement Administration to target suspicious drug distributors.

The powers were stripped in a 2016 bill after heavy influence from the pharmaceutical industry, according to a report in the Washington Post. The scandal surrounding the bill, which passed Congress nearly unanimously and was signed into law by former President Barack Obama, caused Rep. Tom Marino, R-Pa., who led the legislation, to withdraw his nomination to serve as President Trump’s drug czar.
