Fahrenthold not only pored over documents and called hundreds of organizations while reporting on the president’s charitable foundation during the 2016 campaign, but he brought readers real-time social media updates and turned to them for additional tips. In October, Fahrenthold also broke the news that Trump boasted about groping women in an unearthed “Access Hollywood” outtake.

It’s the third year in a row that The Post has won the national reporting category, following awards for its coverage of police shootings and Secret Service security lapses.

The New York Times took home the most awards, winning prizes for its reporting on Russian President Vladimir Putin’s efforts to extend power abroad (international) and C.J. Chivers’ profile of a Marine veteran with post-traumatic stress disorder (feature writing). Daniel Berehulak, a freelance photographer, won the breaking news photography prize for his coverage in the Times of the Philippines government’s brutal anti-drug crackdown.

The New York Daily News and nonprofit investigative journalism organization ProPublica won the public service award for reporting on eviction rules in New York City that disproportionately affected minority residents. The Pulitzer Board specifically highlighted the work of reporter Sarah Ryley, who recently left the Daily News for The Trace.

The International Consortium of Investigative Journalists, McClatchy and The Miami Herald won the explanatory award for reporting on the “Panama Papers,” a collaborative reporting effort that included over 100 media outlets around the world. More than 300 journalists investigated a massive leak of documents from a Panama-based law firm and revealed how major corporations and global leaders us this tax haven to hide their money.
