Lawmakers from both parties are calling on Congress to restrict Trump's use of force in Iran, fearing escalation of the conflict.

A group of US lawmakers, both Democrats and Republicans, are calling on Congress to limit President Trump's military actions in Iran to prevent an escalation of the conflict. Sen. Tim Kaine is proposing a measure that would require a congressional declaration of war to continue hostilities. While Republican leaders support military action, there are voices that dispute the need for it, pointing to the lack of an immediate threat. Trump, on the other hand, is reaffirming his authority to act unilaterally, while divergence among Republicans is growing.
