For Hillary Rodham Clinton, the Citizens United struggle is personal.
The name of the conservative advocacy group has become shorthand for talking about money in politics ever since the organization won a Supreme Court case five years ago that led to the creation of super PACs.
Clinton's relationship with Citizens United dates to her husband's first campaign for president.
As a small, upstart group in 1992, Citizens United published a paperback attacking Bill Clinton. The book, "Slick Willie," was part of a yearlong campaign to derail his presidential candidacy, and the group has been dogging the Clintons ever since.
Hillary Clinton wants to undo the effects of the Citizens United ruling. She's outlining Tuesday how, as president, she'd tackle what she calls "secret, unaccountable money" in politics.
