(Video: Rich Marosi/Robert J. Lopez) I spent 22 years at the Los Angeles Times, where I worked on investigative and multimedia projects across the United States and in Mexico and Central America. I had a wonderful career and was part of a team of reporters that won the 2011 Pulitzer Prize for Public Service for exposing government corruption in Bell, a small city southeast of Los Angeles. But I was offered a great job and realized that it was time to take on a new and exciting challenge.
