(ABC News) Special counsel Robert Mueller has now lost a second official that he brought in from the FBI to help investigate Russia’s alleged meddling in last year’s presidential election, ABC News has learned.

The latest FBI veteran to leave, Lisa Page, was described by media accounts in June as a trial attorney with “deep experience [in] money laundering and organized crime cases.” She was part of what Wired magazine called Mueller’s “investigatory dream team.”

But weeks ago, Page left the Special Counsel’s office and returned to work in the office of the FBI’s general counsel, sources said. 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.
