Amid a conflict of interest scandal that is sweeping through the $85 billion student loan industry, Rep. George Miller asked the White House to turn over e-mails and other records, including those of Education Secretary Margaret Spellings, previously a White House domestic policy adviser.

Miller, of California, also wrote to Spellings seeking records from her as well as former Education Secretary Rodney Paige, former Paige adviser Beth Ann Bryan and other staffers.

He also asked for documents on administration oversight of Reading First, a reading program that is a key part of U.S. President George W. Bush's No Child Left Behind education law.

Spellings is scheduled to testify on May 10 before Miller's House Education and Labor Committee.

Congress and state attorneys general are probing allegations of misconduct across the student loan industry. Investigators accuse some college financial aid officers of taking payments and perks from lenders in exchange for placing the companies on "preferred lender" lists shown to students.

Student Lending Works, an Ohio nonprofit lender, said on Tuesday it has been left off all but 12 of 100 such lists.

"We believe that the 'preferred lender' list system is broken and needs fixing. It no longer serves the interests of students and their families," the organization said. - DDNews India
