The House has voted 407-12 to increase health care spending for veterans.
But the bill is not a done deal yet.
Earlier this week President Barack Obama said he will veto the spending bill if it passed in the House.
The $148 billion measure is for veterans' programs and construction projects at military bases. Roughly half of that is for veterans' pensions and disability payments.
The Associated Press reported this week that 45 percent of the 1.6 million veterans from the wars in Iraq and Afghanistan are now seeking compensation for injuries they say are service-related.
The veto promise comes because House GOP leaders broke with last summer's budget deal by cutting overall funding for agency operating budgets by $19 billion, almost 2 percent.
The veto promise doesn't find fault with the funding levels in the veterans' measure itself. Instead, it says that the GOP moves on spending will force deep cuts to domestic programs like education, research and health care in subsequent legislation.
