Watch live: Trump delivers high-stakes Iran war update

President Donald Trump was set to address the nation on Wednesday as the war in Iran raged on for its sixth week. The war began in late February after the U.S. and Israel conducted a coordinated bombing campaign that killed several of Iran's top military and political leaders. Trump has offered shifting explanations for the war, from ensuring the Iranian regime does not develop a nuclear weapon to offering the Iranian people an opportunity to create a democratic government. Trump's Pentagon has also asked Congress to approve $200 billion to fund continued war efforts, even though Trump has said the war would be over within the next "two to three weeks."
