WASHINGTON — Key members of Congress are demanding a swift vote on a war powers resolution that would restrain President Donald Trump’s military attack on Iran unless the administration wins their approval for what they warn is a potentially illegal campaign that risks pulling the United States into a deeper Middle East conflict.
Both the House and Senate, where the president’s Republican Party has a slim majority, had already drafted such resolutions long before the strikes Saturday. Now they are ready to plunge into a rare war powers debate next week that will serve as a referendum on Trump’s decision to go it alone on military action without formal authorization from Congress. “Has President Trump learned nothing from decades of U.S. meddling in Iran and forever wars in the Middle East?” said Sen. Tim Kaine, D-Va., a leader in the bipartisan effort. He said the strikes on Iran were “a colossal mistake.”In the House, Reps. Ro Khanna, D-Calif., and Thomas Massie, R-Ky., are demanding Congress go on record with a public vote on their own bipartisan measure. “Congress must convene on Monday to vote,” Khanna said, “to stop this.”But most Republicans, particularly their leaders, welcomed Trump’s move against Iran. Many cited the longtime U.S. adversary’s nuclear programs and missile capabilities as requiring a military response.“Well done, Mr. President,” said Sen. Lindsey Graham, R-S.C. “As I watch and monitor this historic operation, I’m in awe of President Trump’s determination to be a man of peace but at the end of the day, evil’s worst nightmare.” Sen. Lisa Murkowski, R-Alaska, commended the troops who executed the mission and thanked allies for their coordination. “There is no question that Iran’s brutal regime must be held accountable for its ongoing aggression abroad and its ruthless repression of its own people,” she said inSaturday morning. “Last summer, following Operation Midnight Hammer, I supported the administration’s targeted actions in Iran after receiving a comprehensive briefing from senior officials. Events are rapidly unfolding, and I expect Congress to receive the same level of engagement so we fully understand the scope, objectives, and risks of any further military action.The administration’s decision to launch, with Israel, what appears to be an open-ended joint military operation aimed at changing the government in Tehran is testing the Constitution’s separation of powers in deep and dramatic ways. Nearly two months earlier, Trump ordered U.S. strikes that toppled Venezuelan leader Nicolás Maduro.While presidents have the authority as the commander in chief to conduct certain strategic military operations on their own, the Constitution vests Congress with the power to wage war. Before the Iraq War began in March 2003, Republican President George W. Bush made a monthslong push to secure congressional authorization. No such vote was attempted on Iran, and an earlier Senate effort to halt Trump’s actions after last summer’s strike on Iran failed. The congressional debate over war powers would mostly be symbolic. Even if a resolution were to pass the narrowly split Congress, Trump likely would veto it and Congress would not have the two-thirds majority needed to overturn that rejection. Congress has often failed to block other U.S. military actions, including in a Senate vote on Venezuela, but the roll calls stand as a public record.The response by House Speaker Mike Johnson reflected the party’s long-standing views. Iran, he said, is facing “the severe consequences of its evil actions.” Johnson, R-La., said the leaders of the House and Senate and the respective intelligence committees had been briefed in detail earlier in the week that military action “may become necessary” to protect U.S. troops and citizens in Iran. He said he received updates from Secretary of State Marco Rubio and will stay in “close contact” with Trump and the Defense Department “as this operation proceeds.” Senate Majority Leader John Thune, R-S.D., commended Trump “for taking action to thwart these threats.”Thune said he looked forward to administration officials briefing all senators — a signal that lawmakers are seeking more answers to their questions about Trump’s plans ahead.Many Democrats are calling the operation illegal, saying the Constitution gives Congress alone the power to declare war. To them, the administration has failed to lay out its rationale or plan for the military strikes, and the aftermath. Sen. Chris Van Hollen, who serves on the Senate Foreign Relations Committee, said the president has undertaken “illegal, regime-change war against Iran.” “This is not making us safer & only damages the US & our interests,” Van Hollen, D-Md., said in a social media post. “The Senate must immediately vote on the War Powers Resolution to stop it.” House Democratic leader Hakeem Jeffries of New York said while Iran is a “bad actor and must be aggressively confronted” for its human rights abuses and the threat it poses to the U.S. and allies, the administration ”must seek authorization for the preemptive use of military force that constitutes an act of war.” New York Sen. Chuck Schumer, the Democratic leader, demanded that Congress be briefed immediately on the administration’s plans. “Iran must never be allowed to attain a nuclear weapon but the American people do not want another endless and costly war in the Middle East when there are so many problems at home,” he said.ADVERTISEMENT
