Mitt Romney, the presumptive Republican nominee for president, on Sunday evening vowed at a closed-door fund-raising event that he would substantially shrink the Education Department if he is elected, NBC News reported. In his campaign, Romney has not made many policy proposals on education. But he was more detailed Sunday in outlining two possibilities for the Education Department. "The Department of Education: I will either consolidate with another agency, or perhaps make it a heck of a lot smaller. I'm not going to get rid of it entirely," Romney said. He said that one reason to keep the agency was to have a federal role in pushing back against teachers' unions.
