Zainab Ahmad, a veteran terrorism prosecutor who recently served on the special counsel team investigating Russian interference in the 2016 election, is joining Gibson, Dunn & Crutcher in New York as a white-collar partner.

Ahmad joined Mueller’s team in 2017 from the U.S. attorney’s office in Brooklyn, where she burnished a reputation as a prosecutor who traveled the world building terrorism cases, collecting evidence and testimony overseas. She won convictions against members of Al Qaeda and the Islamic State in Iraq and Syria, the group commonly known as ISIS.
