"I support finding ways to smartly streamline the refinance process, but I'm not sure that eliminating all documentation requirements makes sense," said GOP Sen. Bob Corker of Tennessee, a committee member. "I also think we need to quickly move beyond short-term stimulus and start focusing on the structural issues in our housing finance system."
Sen. Mike Crapo, the committee's top Republican, declined through a spokeswoman to comment on the bill.
Welch's House bill also died during the last Congress. Welch accused Republicans of not wanting to give Obama an election-year boost by passing the mortgage refinance measure.
"Last year was even tougher because it was an election year," said Welch. "The Republican leadership wanted Obama to fail."
