Bill Clinton broke several months of seeming restraint on his wife’s campaign trail Sunday by going after the “sexist” attacks waged against her by Democratic primary rival Bernie Sanders and his supporters. “When you’re making a revolution, you can’t be too careful with the facts,” the former president said at a rally in Milford, New Hampshire, referencing the democratic-socialist senator’s penchant for “revolutionary” talk. Clinton also dismissed Sanders as “hermetically sealed,” and repeatedly mocked his critique of the Clintons as being a “tool of the establishment.”
