In a likely precursor to future legal action, a lawyer for former FBI Deputy Director Andy McCabe opened a new legal front in his client’s ongoing dustup with his ex-employer.

McCabe counsel David Snyder filed a Freedom of Information Act lawsuit against the FBI and the U.S. Department of Justice Tuesday. Snyder is a partner at Boies Schiller Flexner who has experience representing global and Fortune 500 companies. McCabe retained Boies Schiller earlier this year to work alongside his lawyer Michael Bromwich, senior counsel at litigation boutique Robbins, Russell, Englert, Orseck, Untereiner & Sauber.
