Scott Zamost is senior investigative producer at CNN where he has worked since 2008.

He is a two-time winner of the Investigative Reporters and Editors (IRE) Award and a frequent speaker at IRE and international investigative reporting conferences.

His investigations have ranged from government fraud to war crimes in Iraq.

Among his stories is "Rehab Racket," a groundbreaking investigation into massive fraud in taxpayer-funded drug rehab. The three-part series, a yearlong collaboration with The Center For Investigative Reporting, resulted in clinic suspensions and referrals for possible criminal prosecution, a statewide audit and government oversight hearing.

In 2015, he produced a series of investigative reports on aviation security that revealed only two major U.S. airports fully screen employees.

He revealed misconduct at the FBI by obtaining years of confidential disciplinary reports. At CNN, he has produced both investigative reports and documentaries, including the award-winning "Killings At The Canal: The Army Tapes." The hour-long special investigated the reasons behind the execution of Iraqi detainees by American soldiers.

"Prescription For Cheating" revealed how doctors got away with cheating on their medical board exams. "Post Office Mansion" showed how the U.S. Postal Service was purchasing expensive homes to relocate executives that cost millions of dollars in taxpayer money.

Prior to CNN, he was the investigative producer at WTVJ/NBC 6 and WPLG-TV in Miami. He was also a producer at CBS News for "Public Eye With Bryant Gumbel," where he tracked down accused war criminals living in Florida.

At WTVJ/NBC 6, he was the first to obtain photos of the 9/11 hijackers, and produced the award-winning "Citizenship For Sale," an investigation about how illegal immigrants were traveling from around the country to South Florida to buy memberships in an Indian tribe as a so-called way to become U.S. citizens. The operator of the scam was prosecuted and went to jail.

He has spoken for the past 14 years at the national IRE conference and also was a speaker at the Global Investigation Journalism Conference in Rio de Janeiro and the SKUP investigative reporting conference in Norway.

He has won dozens of awards including three national Emmy nominations, 23 regional Emmys, two National Headliner awards, three Gold Medals in the New York Festivals awards, the CINE Golden Eagle for investigative reporting, three national Clarion awards, five Edward R. Murrow awards, a National Press Club award, an Alfred I. duPont-Columbia University finalist, the Genesis Award, two Florida Associated Press "Best of Show" awards, the SPJ Green Eyeshade grand prize, seven SPJ Green Eyeshade first place awards and six SPJ Sunshine State awards.

Before his television news career, he was a newspaper reporter, starting at the Las Vegas Sun where he was an investigative reporter and the gaming editor. The Nevada Press Association awarded him the "Outstanding Young Journalist of the Year."

He is a graduate of Northwestern University.
