Clinton’s personal lawyer David Kendall writes a letter to the State Department claiming that Clinton’s “use of personal email was consistent with the practices of other secretaries of state.” Kendall points in particular to Colin Powell, who appears to be the only other secretary of state to use a private email account while in office. But Powell had a government email account in addition to private one.
According to the Washington Post, “Powell conducted virtually all of his classified communications on paper or over a State Department computer installed on his desk that was reserved for classified information, according to interviews.” He also had a phone line installed in his office solely to link to his private email account, which he generally used for personal or non-classified communication. The State Department’s inspector general did find that Powell’s personal email account had received two emails from staff that contained “national security information classified at the ‘secret’ or ‘confidential’ levels.” (The Washington Post, 3/27/2016)
It will later come out that the two emails were at the lowest ‘confidential’ level and did not actually contain any intelligence but were classified for other reasons. (ABC News, 3/4/2016)
