The Pentagon is asking Congress for another $200 billion for the war on Iran, which is almost a quarter of the annual U.S. defense budget.

Democrats are largely, and predictably, against it.

But what about Republicans? While many say they support the president's war (and they certainly do not want to allow a vote on it), Republicans in varying degrees embraced the mantle of fiscal conservatism. This supplemental request would be in addition to the more than a trillion approved late last year, including a $150 billion add-on, money that the Pentagon is still struggling to spend?

Policy Analyst Gabe Murphy at Taxpayers for Common Sense told RS, "Lawmakers are rightly balking at supplemental war funding. The ink is barely dry on the Pentagon's first trillion-dollar budget. A $200 billion supplemental would be a 20 percent kick, so either the Pentagon is using the war as an excuse to grab even more taxpayer dollars, or it's planning for a long-term war. Either way, lawmakers should oppose it."
