The president also has the power to issue executive orders, which are directives that have the force of law and can be used to implement policy changes without congressional approval. Furthermore, the president is expected to serve as a symbol of national unity and leadership, representing the values and ideals of the American people. This includes giving speeches, attending public events, and meeting with citizens to address their concerns. The president also has the important responsibility of leading the country in times of crisis, whether it be a natural disaster, a terrorist attack, or a public health emergency.
