Mary Daly served as the Director of Opioid Enforcement and Prevention Efforts in the Justice Department for one year, beginning in February of 2018. The position was created in December of 2017.

Then-Attorney General Jeff Sessions praised Daly in a news release announcing her hiring. “In the midst of the deadliest drug crisis in American history, we need to prosecute drug crimes aggressively and use our resources wisely. That’s why today I am happy to announce that Mary Daly will help the Department of Justice coordinate our anti-opioid efforts. Mary is a talented and experienced prosecutor and she will help us act as effectively as possible in this time of crisis.”

Daly echoed the “aggressive” stance upon taking the job. She advocated for strict policies to curb the opioid crisis. CBS News reported that Daly supported Sessions’ decision to reverse a policy by the Obama administration that cut or reduced sentences for non-violent, lower-level drug offenders. Daly told CBS in April of 2018, “We need to use tough prosecutions if we are going to get our way out of this epidemic. We don’t ignore the need for prevention and treatment efforts, but the notion that tough enforcement is the wrong approach is wrong.”
