At least 22 phones used by members of special counsel Robert Mueller’s team had all of their data wiped before an official could review the devices for records, according to documents released on Sept. 10 by the Department of Justice.
Some of the phones were wiped by accident. Others were reset after the users entered the wrong password too many times. A phone belonging to assistant special counsel James Quarles “wiped itself without intervention from him,” according to the documents (pdf).
