As Rick Santorum presses for the conservative votes he needs to overtake GOP presidential front-runner Mitt Romney, the former senator hammers away at the role state and federal governments play in running schools.

Santorum plays up how he and his wife have home-schooled their
seven children and says parents should be the ones responsible for
educating their kids.

Yet back when Santorum was a senator from Pennsylvania, he got a Pittsburgh-area school district to help pay tens of thousands of
dollars in tuition for his children to receive online schooling.

Santorum's campaign isn't responding to questions about his
family's online instruction. It's not known whether his children received teaching at home in addition to what they got online.
