His office was also involved in investigating Russia's alleged efforts to influence last year's presidential election, including hacking of Democratic National Committee computers. It's unclear why Strzok stepped away from Mueller's team.

Lisa Page, described as a trial attorney with “deep experience [in] money laundering and organized crime cases,” left around the same time as Strzok and returned to work in the office of the FBI’s general counsel, a spokesperson for the special counsel confirmed to ABC News in September. According to one source, Page joined Mueller’s team on a short, temporary assignment and always expected to return as soon as that assignment ended.
