Colin Powell and Condoleezza Rice used private accounts for classified emails

Hillary Clinton's campaign has seized on findings that Rice and Powell were sent sensitive national security information to nongovernment email addresses

Hillary Clinton's campaign claimed vindication in the long-running emails saga on Thursday when it emerged that two Republican secretaries of state had also received information later deemed classified on personal accounts.

The state department watchdog found that both Colin Powell and Condoleezza Rice, America's top diplomats under president George W Bush, were sent sensitive national security information to nongovernment email addresses.
