Rep. Tom Marino, R-Pa., has withdrawn his name from consideration as America's drug czar, President Trump said Tuesday. Marino is stepping back days after reports that legislation he sponsored hindered the Drug Enforcement Administration in its fight against the U.S. opioid crisis.A joint report by The Washington Post and 60 Minutes found that Marino's measure "helped pump more painkillers into parts of the country that were already in the middle of the opioid crisis," as NPR's Kelly McEvers said earlier this week. The bill had been opposed by the DEA and embraced by companies in the drug industry.As NPR's White House Correspondent Tamara Keith notes, Marino's withdrawal leaves the Trump administration without nominees for several important domestic roles, including drug czar, the director of the DEA, and secretary of Health and Human Services.Marino was a main backer of the Ensuring Patient Access and Effective Drug Enforcement Act; among other things, the measure changed the standard for identifying dangers to local communities, from "imminent" threats to "immediate" threats. That change cramped the DEA's authority to go after drug companies that didn't report suspicious — and often very large — orders for narcotics.After the Post and 60 Minutes report, several members of Congress called for the White House to pull Marino's nomination as drug czar.Sen. Joe Manchin, D-W.Va., said he was "horrified" by the story, adding that he "cannot believe the last administration did not sound the alarm on how harmful that bill would be for our efforts to effectively fight the opioid epidemic."In a letter to the president, Manchin wrote about the ability of wholesale drug distributors to send millions of pills into small communities:"As the report notes, one such company shipped 20 million doses of oxycodone and hydrocodone to pharmacies in West Virginia between 2007 and 2012. This included 11 million doses in one small county with only 25,000 people in the southern part of the state: Mingo County. As the number of pills in my state increased, so did the death toll in our communities, including Mingo County."After Marino's name was withdrawn, Manchin tweeted to Trump, "thanks for recognizing we need a drug czar who has seen the devastating effects of the problem."Manchin has co-sponsored legislation that would repeal the changes made by the 2016 law, along with Sen. Claire McCaskill, D-Mo., and Sen. Margaret Wood Hassan, D-N.H.In the Senate, the drug enforcement bill was sponsored by Sen. Orrin Hatch, R-Utah — who also saw it through the markup process. In Congress and on Twitter, Hatch has defended his role this week, calling the Post story "flawed" and "one-sided."Hatch also said the bill was supported by patient groups who "were concerned about DEA's unfettered enforcement authority.""I spent months negotiating with DEA and with DOJ until they were at a point where they were comfortable allowing the bill to proceed," Hatch said Monday on Capitol Hill. "If they had asked me to hold the bill or to continue negotiations, I would have done so."Hatch noted via Twitter that "President Obama signed this bill into law. DEA and DOJ, who work for the President, could have urged him to veto it. They did not."Tens of thousands of Americans are dying from drug overdoses each year. In its preliminary report about the opioid crisis, President Trump's Commission on Combating Drug Addiction and the Opioid Crisis said in August that "with approximately 142 Americans dying every day, America is enduring a death toll equal to Sept. 11 every three weeks."In an interview with NPR, here's how Post reporter Scott Higham described the way in which Marino's bill became law:
