Tillerson's use of the alias became publicly known in March 2017, after New York State Attorney General Eric Schneiderman wrote in a letter to a judge that Tillerson had used the "Wayne Tracker" email for at least seven years. Later that month, Exxon revealed that emails from the alias account from September 2014 to September 2015 were missing; a further search recovered some emails, but none between September 5, 2014, and November 28, 2014. An attorney for Exxon said a "unique issue" limited to that account led to emails being automatically deleted.
