FBI Director Argued for WhatsApp Encryption in Prior Legal Practice

FBI Director Christopher Wray, who has been pushing tech companies to give law-enforcement authorities access to encrypted messages, once advocated the opposite view when representing Facebook Inc.’s WhatsApp in a legal case involving the messaging service’s use of such technology, according to a new court filing. Mr. Wray was involved in the legal matter, which remains under seal, before he took the top job at the Federal Bureau of Investigation while he was employed as a partner at King & Spalding LLC, Facebook said in a court filing.
