Former First Lady and former U.S. Secretary of State has acknowledged that the questions about her use of a private email server have contributed to growing questions about whether American voters can trust her.

In an exclusive interview with NBC News' Andrea Mitchell, Hillary Clinton apologized for the confusions over her email and she made a poor choice.
IN: "At the end...
OUT: ...best choice."
