Sparring with Rep. Paul Ryan, R-Wis., over the administration’s 2013 fiscal plan, Geithner rejected criticisms that the budget did not do enough to address the country's long-term debt.
"You're showing that you have no plan to avert a debt crisis," Ryan said.
But Geithner argued that gridlock on current issues takes precedence over future problems.
"If we can't agree on how to solve the problems of the next 10 years, then why are you focused on the next 100 years?" Geithner said during the heated exchange.
Also at issue was tax reform. The president's budget would increase tax revenues by $1.9 trillion, primarily by increasing the marginal tax rate on high-income households.
Geithner has made previous comments that he supports lowering rates and broadening the tax base. But GOP lawmakers pointed to the budget's increase of rates and keeping the current framework.
"The system is too complex today, and you're bringing us an even more complex system," Rep. Scott Garrett, R-N.J., said. "Where is your tax reform plan?"
"If you want to bludgeon me into admitting that we're not going to give a tax reform plan in this budget, I confess," Geithner shot back.
Geithner repeatedly emphasized that the administration wants to take a "balanced approach" in tackling the deficit by increasing revenue through taxation and cutting spending in targeted areas while still maintaining "key investments."
"We have to govern with limited resources and use those resources more wisely," Geithner said.
But Geithner took issue with the Republicans’ aversion to tax increases, even on high-income earners.
"You can not govern responsibly if you commit to never raise taxes," Geithner said.
