The United States Senate backed legislation on Thursday to limit President Donald Trump’s ability to wage war against Iran, rebuking the president after a strike against an Iranian military commander and Tehran’s retaliation last month raised fears of broader regional conflict.
The measure, authored by Senator Tim Kaine, says Trump must win approval from Congress before engaging in further military action against Iran. Eight Republicans joined with Democrats to pass the resolution by a 55-45 vote.
Kaine and other supporters said the resolution was not about Trump or even the presidency, but instead was an important reassertion of congressional power to declare war.
While Trump and other presidents “must always have the ability to defend the United States from imminent attack, the executive power to initiate war stops there”, Kaine said. “An offensive war requires a congressional debate and vote.”
Trump veto expected if House passes
The Democratic-controlled House passed a separate, nonbinding war powers resolution last month. The House could take up the Senate resolution later this month, said House Majority Leader Steny Hoyer.
Two-thirds votes in the House and Republican-run Senate would be needed to override an expected Trump veto.
Answering a claim by some of Trump’s supporters and Trump himself that the measure would send a signal of weakness to Iran and other potential adversaries, Kaine said the opposite was true.
“When we stand up for the rule of law – in a world that hungers for more rule of law – and say ‘this decision is fundamental, and we have rules that we are going to follow so we can make a good decision,’ that’s a message of strength,” Kaine said.
Republican Senator Mike Lee agreed. Lee supports Trump’s foreign policy, including towards Iran, but said Congress cannot escape its constitutional responsibility to act on matters of war and peace.
