The primary function of the executive branch is to implement and enforce laws passed by the legislative branch. Headed by the President, the executive branch administers federal policies, oversees government agencies, and conducts foreign relations. This branch also holds the power to issue executive orders, manage the national budget, and ensure national security through various agencies, including the Department of Defense and the Department of State. The executive branch's effectiveness is crucial for translating legislative goals into tangible outcomes, reflecting the administration's vision for the country.
