US lawmakers have voiced strong reactions after reports emerged that the Pentagon is planning a multi-week ground operation in Iran. Republican Senator James Lankford, speaking on NBC’s ‘Meet the Press,’ said it is essential to understand why troops are being deployed. He added that whether President Donald Trump needs congressional approval depends on how the forces would be used.

Democratic Senator Cory Booker of New Jersey warned that Trump is pushing the country into a conflict without congressional authorization and without a clear exit strategy. Maryland Senator Chris Van Hollen told ABC News’ ‘This Week’ that the war is costing American lives and billions of dollars daily, while also driving up oil and gas prices.

The debate underscores growing concern in Washington about the potential escalation of the Iran conflict and the constitutional limits on presidential war powers.
