Vice President Kamala Harris is being pressed by a top state official in Oklahoma to back a reimbursement for the cost to taxpayers of illegal immigration and its impact on schools, according to a letter.

In a letter on Tuesday to Harris and the White House, Oklahoma schools Superintendent Ryan Walters criticized the Biden-Harris administration for its “abject failure to secure the border and enforce immigration law.” Citing data from the Washington, D.C.-based Federation for American Immigration Reform, the Republican requested a reimbursement of almost $475 million for “the financial impact borne by Oklahoma taxpayers for education of illegal immigrant children.”
