(THEHILL) — Senate Republicans on Wednesday blocked an effort by Sen. Elizabeth Warren (D-Mass.) to attach an amendment aimed at lowering student loan rates to the budget.

Senators voted 46-53 against Warren’s amendment to the Republican budget resolution.

Warren’s amendment would have allowed people with college loan debt to refinance at interest rates from the 2013-2014 academic year. The Massachusetts Democrat, who is rejecting calls to run for president, said the move would allow undergraduates to refinance their loans to a 3.9 percent interest rate, with a “slightly higher” rate for graduate students.

“Millions of borrowers are still stuck paying interest rates at 6 percent, 8 percent, 10 percent and even higher,” she said.

Her plan would have been paid for by requiring millionaires to pay at least a 30 percent effective federal tax rate.
