Schumer criticizes lack of clear rationale for war in Iran: 'Which one is it, Donald Trump?'

Sen. Chuck Schumer, D-N.Y., criticized the administration for failing to give a clear rationale for war in Iran.

"If the case for war was strong, the story would be consistent and steady. Instead, it changes by the hour," Schumer said on the Senate floor.

"We heard this attack was defensive in nature. Then (Secretary of State Marco) Rubio said it was preemptive. Which one is it, Donald Trump? Regime change? Nuclear weapons? Missiles? An imminent threat to the homeland? Or a preemptive strike to stop future attacks on the region?" Schumer said. "When the rationale for war keeps shifting, the strategy is missing. And that's because there is no strategy. And when the strategy is missing, the risk grows."

Schumer warned against engaging in a prolonged contact.

"This is not a defensive war. This is not a necessary war. This is a war of choice," he said.

Schumer said Americans would prefer Trump focus on lowering costs at home.
