(CNN) — Top Capitol Hill Democrats, and a small number of Republicans, watched in alarm Saturday as the US launched a major assault on Iran, decrying President Donald Trump’s call for the overthrow of another foreign government without their expressed approval.
Trump ordered the strikes on Tehran just days before the GOP-led House and Senate are each set to formally debate and vote on US military action in Iran. Democrats, along with at least three Republicans, say the president’s decision, with lawmakers scattered across the nation and not planning to return to Washington for days, raises serious questions about the legality of the attack.
“It’s a slap in the face of the United States Congress. The president has launched an illegal war when there is no imminent threat. He did not consult with Congress or allow for a debate in Congress, which even George W. Bush did,” Democratic Rep. Ro Khanna of California told CNN on Saturday morning.
Now, House and Senate Democratic leaders — as well as the famously anti-interventionist Republican Rep. Thomas Massie — are demanding that GOP leaders bring Congress back into session immediately to hold a formal vote on the unfolding conflict in Iran.
“I am opposed to this War. This is not ‘America First,’” said Massie of Kentucky.
“The Constitution conferred the power to declare or initiate war to Congress for a reason, to make war less likely,” Sen. Rand Paul, a leading Republican in the Senate effort to curb Trump’s war authority, similarly declared, adding that his “oath of office is to the Constitution, so with studied care, I must oppose another Presidential war.”
Those votes to require congressional approval for military action against Iran, which were already set for midweek, will amount to a major test of loyalty for some of the GOP’s far-right flank, who have for years championed Trump’s promise of keeping America out of foreign wars. Those Republicans will be forced to take a public stance after months of simmering consternation over Trump’s legal authority as he has dramatically expanded powers abroad with Congress on the sidelines.
Multiple GOP sources told CNN they believe those three Republicans — Massie, Paul and Rep. Warren Davidson, who has also publicly condemned the attack without authorization — are likely on an island in their own party. Even so, Democrats believe it might be enough to deliver the rebukes.
“I do think this has a real chance of passing. And it’s going to be seen like the Iraq war vote,” Khanna added, referring to the historic 2002 vote in Congress that authorized the US invasion of Iraq.
Even if the measure passes, it is subject to a presidential veto, and a two-thirds vote to override could be a challenge to reach. So while it would be unlikely to change the president’s actions, it would be seen as a stunning rebuke of the administration.
One Republican, speaking to the CNN on the condition of anonymity because they had received classified briefings on the operation, fiercely disputed that Trump was leading the nation into another conflict akin to the Iraq War. The person believed there was wide support in the party for the president’s actions.
Indeed, dozens of Republicans were quick to praise Trump’s actions on
