A White House official who now chairs Hillary Clinton’s campaign once asked Clinton’s chief of staff, Cheryl Mills, if she had a “personal email” where he could send her some materials outside the State Department’s official channels.

John Podesta, then President Obama’s counselor, emailed Mills’ government account in Sept. 2009 to ask if she had a personal address and informed her that he was planning to meet with “Rahm,” likely Obama’s then chief of staff Rahm Emanuel.
