Former US President Bill Clinton likened the controversy over his wife Hillary Clinton's use of a personal email account while secretary of state to the same Republican and media tactics to stir controversy during his presidency, according to an interview made public on Saturday.Hillary Clinton, who was the Democratic frontrunner when she announced her bid for the White House in April, has faced increasing scrutiny over her email use, including a personal computer server set up at her home in New York, and faces several inquiries in the Republican-controlled Congress."It always happens. We're seeing history repeat itself," her husband, who served two terms from 1992 to 2000, told CNN's "Fareed Zakaria GPS" program."The other party doesn't want to run against her. And if they do, they'd like her as mangled up as possible," Bill Clinton said in excerpts of the interview. The full exchange is scheduled to air on Sunday."I have never seen so much expended on so little," he added.Hillary Clinton has apologized over the email issue and has said she had turned over all her work emails from her time as the nation's top diplomat for the State Department to review and make public, which it is doing in batches.
