"This is a bipartisan bill supported by over 50 Republicans," Obey said. "There has been virtually no criticism of its contents. It is clear the only reason the president vetoed this bill is pure politics."
Since winning re-election, Bush has sought to cut the labor, health and education measure below the prior year level. But lawmakers have rejected the cuts. The budget that Bush presented in February sought almost $4 billion in cuts to this year's bill.
and this:
Much of the increase in the defense bill is devoted to procuring new and expensive weapons systems, including $6.3 billion for the next-generation F-35 Joint Strike Fighter, $2.8 billion for the Navy's DD(X) destroyer and $3.1 billion for the new Virginia-class attack submarine.
Huge procurement costs are driving the Pentagon budget ever upward. Once war costs are added in, the total defense budget will be significantly higher than during the typical Cold War year, even after adjusting for inflation.
