David Fahrenthold says he is incredibly grateful for the win
A Washington Post reporter who uncovered crude remarks by US President Donald Trump during his campaign has been awarded a Pulitzer Prize.
David Fahrenthold won the prize for National Reporting into Mr Trump's charity work.
Shortly after the Iowa caucuses, Fahrenthold set out to learn what had become of the US$6m (€5.65m) Mr Trump said he had raised for veterans, including US$1m of his own money.
Fahrenthold soon discovered, The Washinton Post reports, that the then-candidate had stopped distributing money despite having given out just a fraction of what he raised.
That was the start of a reporting effort that eventually expanded to cover all of Mr Trump’s charitable giving.
His work also included the article that disclosing crude comments made by Mr Trump, where he bragged about groping women during an unaired portion of an interview on 'Access Hollywood' in 2005.
Speaking to host Billy Bush off-camera, Mr Trump said: "You know I'm automatically attracted to beautiful - I just start kissing them. It's like a magnet. Just kiss. I don't even wait.
"And when you're a star, they let you do it. You can do anything. Grab them by the p**y - you can do anything."
Fahrenthold also invited his Twitter followers to help him report stories, asking for help in tracking down details of Mr Trump’s past.
He posted photographs of his reporter's notebook on Twitter, asking readers to suggest more charities to call.
On hearing the news of his win, Fahrenthold said: "What a wonderful day! Thank you all for the good wishes today, and thanks to everyone who helped last year. I'm so incredibly grateful".
