Four members of The Washington Post staff won George Polk journalism awards for work published last year, it was announced Sunday.

The award for political reporting went to David A. Fahrenthold for articles he wrote during the presidential campaign about activities that Donald Trump had tried to keep from public view.

Fahrenthold was cited for a “dogged pursuit” of Trump that led to a year-long string of articles offering a picture “that Trump had long sought to keep secret.”

In announcing the 68th annual Polk awards, Long Island University said that Fahrenthold unmasked “deceptive and illegal charitable activities” on the part of Trump’s foundation.

The university said that Fahrenthold’s work also led to “a blockbuster — the existence of a video” in which Trump “bragged about sexually assaulting women.” It shaped political discourse for days, the university added.

The award for medical reporting went to reporters Lenny Bernstein and Scott Higham and editor David Fallis for tracing lax regulation of narcotic painkillers by the Drug Enforcement Administration “to pressure from the pharmaceutical industry and allies in Congress and the Justice Department.”

According to the university, this was despite “rampant addiction” and nearly 180,000 deaths in the United States since 2000. The university credited the work with showing that the industry and its attorneys “apparently sought to mitigate oversight by hiring dozens of DEA officials,” including 31 from a unit charged with keeping prescription drugs off the black market.

Awards were given in 15 categories and showed that even in a “tough year” for journalism, “bright spots” existed, Polk curator John Darnton said.
