President Donald Trump signed an executive order Thursday calling for the dismantling of the U.S. Education Department, advancing a campaign promise to take apart an agency that’s been a longtime target of conservatives. "We're going to shut it down and shut it down as quickly as possible," Trump said before signing the order. "It's doing us no good." Trump has derided the Education Department as wasteful and polluted by liberal ideology. However, completing its dismantling is most likely impossible without an act of Congress, which created the department in 1979. And the White House says the department would not close completely right now. It is to retain certain critical functions, like managing federal student loans and Pell grants. A White House fact sheet said the order would direct Secretary Linda McMahon “to take all necessary steps to facilitate the closure (of) the Department of Education and return education authority to the States, while continuing to ensure the effective and uninterrupted delivery of services, programs, and benefits on which Americans rely.” Trump's action will make the department much smaller than it is today, but it will continue managing federal student loans and Pell grants, White House press secretary Karoline Leavitt said Thursday. Other critical department duties such as enforcement of civil rights will remain, she said, but she did not say how they will be fulfilled.
