What concerns does Arne Duncan express about Linda McMahon's nomination as Education Secretary?

Former Education Secretary Arne Duncan expresses grave concerns that public education in America is 'under assault,' emphasizing that the Department of Education faces 'extraordinary risk' under the Trump administration. He points to the ongoing reading crisis, noting that President Trump has not proposed anything that would help children learn to read better. Duncan fears McMahon's appointment may lead to dismantling public education rather than solving critical challenges. He specifically worries about essential services and funding being 'outboarded' or eliminated, which would impact vulnerable populations including low-income and special needs students. While hoping McMahon comes with 'a pure heart' to create opportunities, he remains deeply concerned about the future direction of American education policy.
