The House passed a resolution Thursday to limit President Trump's ability to engage in hostilities against Iran under the 1973 War Powers Resolution, as Democrats attempt to reassert Congress' constitutional authority to declare war amid a tense standoff with the Islamic Republic.
The vote passed mostly along party lines, with three Republicans joining the Democrats to vote in favor and eight Democrats voting against.
Mr. Trump on Thursday called the strike that killed Iranian Major General Qassem Soleimani "the anti-Benghazi."
"Had they gotten through, we would have had either hundreds of dead people or hundreds of hostages," Mr. Trump said at a rally Thursday night. "That wasn't going to happen. And I called up our great generals, I said get them over there now."
Mr. Trump said Wednesday Iran appeared to be "standing down" after a week of soaring tension between the two countries. By Thursday, however, there were mixed messages. A senior Iranian military commander vowed there would be "harsher revenge" against the United States. The remark came a day after Iran's political leaders said the Islamic Republic had "concluded" its response to Soleimani's killing.
