The Senate and the House are expected to vote on different versions of the budget next week.
"The budget we have now passed out of the Budget Committee preserves the core priorities in President Obama's budget plan," Sen. Kent Conrad, chairman of the committee, said in a statement.
Conrad, D-North Dakota, trimmed the president's original proposal in response to congressional projections showing larger-than-expected budget deficits over the next several years.
Conrad said he had preserved the president's major initiatives in education, energy and health-care reform in the wake of "new realities" on finances without sacrificing the administration's deficit reduction goals.
Obama has pledged to halve the deficit by 2013, a goal Conrad says his budget maintains.
