Greenberg Traurig sought to distance itself from its most high-profile partner, former New York Mayor Rudy Giuliani, after he told Fox News that he was involved in initial planning for President Donald Trump’s executive order barring certain refugees from entering the United States.

Giuliani, who chairs Greenberg Traurig’s cybersecurity, privacy and crisis management practice and is a senior adviser to the firm’s executive chairman, said that Trump asked him to assemble a commission to show him how to legally enact a Muslim ban.
