WASHINGTON, DC – MAY 08: U.S. Sen. Tom Coburn (R-OK) heads into the Senate Republican Caucus policy luncheon at the U.S. Capitol May 8, 2012 in Washington, DC. Moments before, the U.S. Senate voted down a proceedural motion that would have opened debate on The Stop The Student Loan Interest Rate Hike Act of 2012, which would have prevented interest rates on government subsidized Stafford loans to double from 3.4 percent to 6.8 percent on July 1, 2012.
