Hakeem Jeffries predicts failure for US following strikes against Iran

Jeffries responded, "John Fetterman knows better."

"Article 1 of the Constitution explicitly provides Congress with the authority to declare war, period, full-stop. And the framers of the Constitution made that decision because they were concerned about kings throughout time getting their people into unnecessary wars, impoverishing them or imperiling their very well-being by sending them off to a foreign conflict," the lawmaker added.

CNN's Bolduan asked the House minority leader if he thought Trump could pull off regime change without boots on the ground.

"No, that's impossible for him to do. Now, he's claiming that he's not going to put U.S. boots on the ground, but he's claimed a lot of things only to do the exact opposite. This is the same person who said he is coming back to the presidency to get America out of endless wars, and now he has just gotten us into a potential endless war in the Middle East of all places, where we know, based on what happened in Afghanistan, based on what happened in Iraq, based on what happened in Libya, it's not going to end well for American interests," he responded.

Several Democrats have spoken out against Trump's decision to strike Iran. 

The White House did not immediately return a request for comment.
