Democratic U.S. Sen. Al Franken will join Massachusetts Sen. Elizabeth Warren at a Capitol Hill press conference today in an effort to drum up support for her bill that would allow an estimated 25 million people with older student loans to refinance that debt at current, lower interest rates.

GOP lawmakers have accused Democrats of trying to capitalize on the student debt issue for election year gains.
