According to Deep Tide TechFlow, on June 16, Democratic senators proposed legislation to prevent Trump from using force against Iran without congressional authorization. The escalation of fighting between Israel and Iran has raised concerns about a wider conflict.
Virginia Senator Tim Kaine has long sought to reclaim Congress's war powers from the White House. In 2020, Kaine introduced a similar resolution to limit Trump's ability to wage war against Iran. The measure passed in both the Senate and the House but failed to withstand a veto from the Republican president.
