Powell, Rice emails were classified later
Evidence says a recent letter writer is mistaken about the email claim. Neither Colin Powell nor Condoleezza Rice used a private server like Hillary Clinton, though they did use a private email account at least some time. None of their messages were deemed classified at the time but were retroactively classified years later.
FBI Director James Comey said some of Clinton’s emails contained data that was classified at the time as well as containing classification markings.
A fair reading of Comey’s testimony supports the claim that Clinton lied about her email use. The rest of the writer’s message is the typical rant of left-leaning people eager to demonize others with their broad-brush diatribes.
