Mr Giuliani, who was famously mayor of NYC at the time of the 9/11 attacks, has been with Texas-based law firm Bracewell & Giuliani since 2005 and built up the New York office to 80 lawyers. The firm, which also has offices in London and Dubai, will now be known as Bracewell.

Mr Giuliani will be the global chairman of Greenberg’s cybersecurity and crisis management group and a senior adviser to the firm’s executive chairman, Richard A. Rosenbaum. He will be joined at Greenberg by another Bracewell lawyer, Marc L. Mukasey, who is assuming the role of global co-chairman of its white-collar defense group. Source: The New York Times
