NBC News has hired  Bill Bratton, the former New York City Police Commissioner and former Chief of the Los Angeles Police Department, as its Senior Law Enforcement and National Security Analyst, starting this week. He will be seen on NBC News and MSNBC.

Until last month, Bratton served as New York City’s Police Commissioner for the second time, to take a job with consulting firm Teneo Holdings, where he will head up a new “risk division,” the Wall Street Journal reported on August.

This also is Bratton’s second tour of duty with NBC News, having served as an analyst for NBC News and MSNBC in 2013.

Here is the memo from NBC News president Deborah Turness and MSNBC president Phil Griffin

We are very pleased to announce that William Bratton, Executive Chairman of Teneo Risk and former New York City Police Commissioner, returns to NBC News and MSNBC as Senior Law Enforcement and National Security Analyst, starting this week. Bill’s singular expertise and incisive analysis on counterterrorism and criminal justice will be an incredible asset across all of our platforms, as you’ve already seen with his recent contributions following the bombings in New York and New Jersey.
As the Executive Chairman of Teneo Risk, Bill advises clients on cyber risk, counterterrorism preparedness and crisis response. Up until last month, Bratton served as New York City’s Police Commissioner for the second time, leading the largest police force in the country. Over the course of his 46-year career in law enforcement, Bratton has also served as the Chief of the Los Angeles Police Department—making him the only person ever to lead the police agencies of America’s two largest cities—as well as Commissioner of the Boston Police Department.
Beyond his career in public service, Bill was an analyst for NBC News and MSNBC in 2013 before he returned to the NYPD in 2014. The return of Bill Bratton brings a very relevant voice of authority to NBC News and MSNBC as we continue to cover counterterrorism and national security. Unfortunately this is an area of coverage that we have had to devote more resources to in recent years, and we know our audiences will benefit greatly from his deep knowledge and peerless experience.
Please join us in welcoming back Bill to NBC News and MSNBC.
