Transcript for Investigation: Emails Say Clinton Staff Put Donor on List for Security Board

A new batch of Clinton e-mails out this morning raising questions about a donor to the Clinton foundation and how he ended up on a government intelligence advisory board. ABC's Brian Ross is here with more. Good morning. Reporter: Good morning, Amy. The newly released state department e-mails being made public here this morning reveal how under secretary of state made someone part of an advisory board even though he had no known experience in the area.
