Caleb Melby is a senior investigative reporter with Bloomberg News. Caleb works in collaboration with journalists across Bloomberg’s global newsroom to report urgent stories that have prompted action from prosecutors, regulators and lawmakers. His reporting on abusive lenders prompted a foreclosure moratorium that kept US veterans in their homes. Exposés on multi-billion-dollar companies triggered government investigations, and led to the firing and jailing of top executives. And he was on the Bloomberg team that revealed how “well-connected individuals perverted the stated intention” of the federal opportunity zone program, winning a George Polk award. He teaches investigative reporting at Columbia University. Photo: Chris Goodney/Bloomberg.
