The Trump administration is ramping up its investigation into the hundreds of millions in foreign funds pouring into U.S. campuses, according to a letter released Friday by the Department of Education.

Investigators launched inquiries in mid-June focused on the foreign money received by Georgetown University and Texas A&M University as the U.S. government steps up its efforts to track foreign influence on U.S. campuses. In an unusual move, the letters to both those schools were placed on the Federal Register earlier today.
