JohnMiller2CBS News correspondent John Miller is leaving the network and joining the NYPD as a new commissioner re-joins the force.”I never stay anywhere too long,” Miller said on WCBS’s 5:30 newscast.

“John, congratulations. Our loss is the city’s gain,” said anchor Dick Brennan.

The New York Post was first to report earlier this month that Miller was looking to make the move. Miller will re-join incoming NYPD Commissioner Bill Bratton. “It’ll be a great challenge that I hope to rise to,” said Miller.

Miller has bounced between jobs as a journalist and in law enforcement his entire career. His first job was as a reporter for WNEW (now Fox5) in New York City. In 1985 he joined WNBC and left 9 years later to join Bratton at the NYPD. He returned to TV news as a correspondent for ABC News in 1995 where he remained for 7 years, being named “20/20″ co-anchor in 2002. Miller left ABC to join Bratton at the LAPD in 2003 where he was head of the Counterterrorism and Criminal Intelligence. He joined CBS News in 2011.
