"We have said if Congress acts on something, we'll keep an open mind," Foxx said.
Instead, Obama is pushing a plan to close tax loopholes and use the revenue to pay for increased transportation spending for the next four years.
"We have a proposal we think is politically acceptable," Foxx said.
House Ways and Means Committee Chairman Dave Camp, R-Michigan, floated a similar proposal in April. But many Republicans say they'd rather offset increases in transportation spending with cuts to other government programs rather than tax increases. And many lawmakers say they want to continue to the trust fund's "user pays" principle by raising money from people who most use the roads, if not through a gas tax then some other means.
Nearly a dozen proposals to address the problem have been floated in Congress, but none have gained traction. House Republicans recently proposed a short-term patch based on savings associated with ending Saturday mail delivery by the postal service. The plan died a quick death when it became clear that many GOP lawmakers wouldn't support it.
Senate Finance Committee Chairman Ron Wyden, D-Ore., offered a plan last week to keep transportation aid flowing for another six months. The plan, which included raising taxes on large trucks, ran into opposition from Republican senators. He dropped the truck tax, but Republicans say they want more spending cuts as part of the package. Further action is expected when Congress returns to work from a Fourth of July break.
In the House, Camp has said he will offer a new plan to shore up the trust fund next week.
