U.S. Defense Secretary Ash Carter used a personal email account for some work-related business earlier this year at the Pentagon, although he has since stopped such use of his personal email, the Pentagon said on Thursday.
The New York Times first reported on Wednesday Carter's use of his personal email account, citing White House and Defense Department officials and copies of the emails.
Carter, who took office in February, continued to use his own email account, contrary to Defense Department rules, for at least two months after it became public in March that Hillary Clinton had used only her personal email account while she was secretary of state, the Times quoted the officials as saying.
