money.cnn.com — Sallie Mae, the nation's largest student lender, spent $640,000 lobbying in the second quarter for government help to shore up the troubled student loan market and on legislation related to other issues affecting the industry, according to a recent disclosure report. The company lobbied on access to capital for student lenders and a variety of legislation touching on student lending, education spending and banking. Congress sets the interest rates borrowers pay and the subsidy levels lenders receive under the federal student loan program. Lawmakers last year cut about $20 billion in federal subsidies to lenders to pay for increases in student aid. That cut into lenders' profits, as did the credit crunch, making it expensive to raise the capital they need to offer student loans.
