Ari Melber has been named MSNBC Chief Legal Correspondent. Melber will remain co-host of the network’s afternoon show The Cycle while reporting on legal policy and law enforcement issues for all of the network’s platforms; NBC News Justice Correspondent Pete Williams will continue to appear on MSNBC.

Melber’s appointment comes while the network is in the midst of a shakeup of its daytime schedule at least, under Andy Lack, who has returned to the company as Chairman, NBC News and MSNBC. The Cycle is one of the programs in that daypart suffering significant ratings drops; one day in March, this show clocked a smaller audience than did Al Jazeera America.

As part of his expanded role, Melber appeared today on Morning Joe to preview a new report on the FBI’s counter-cyber operations in New York.  The full piece will run on The Cycle at 3 PM  ET,  including interviews with the current special agent in charge of cyber, Leo Taddeo, an interview with Taddeo’s predecessor, Mary Galligan, who also led the 9/11 investigation and is one of the highest-ranking women in FBI history, and an interview with Shawn Henry, the former head of cyber operations for the FBI in Washington, DC.
