The secrets of David Fahrenthold's reporting on the Trump Foundation

Washington Post journalist David Fahrenthold is investigating the Trump Foundation -- and simultaneously showing how to involve readers in the reporting process.

Other journalists say Fahrenthold's work is inspiring. Some have dubbed it Pulitzer worthy. Its impact was reinforced on Tuesday when President Obama cited the reporting while stumping for Hillary Clinton.

While the Clinton family foundation "has saved countless lives around the world," Trump's foundation "took money other people gave to his charity and then bought a six-foot-tall painting of himself," Obama said.
