The foreign policy powers of Congress and the president are outlined in the Constitution, with some overlap between the two branches. Congress has the power to declare war, regulate foreign commerce, approve treaties, and confirm ambassadors. The president, on the other hand, is the commander-in-chief of the military and has the power to negotiate and sign treaties, appoint ambassadors, and conduct foreign policy initiatives. Overall, the president has more authority in conducting foreign policy, while Congress plays a significant role in overseeing and regulating the president's actions.
