Introduction Constitution refers to a set of laws on which a state or a nation is governed. It outlines the provisions for the powers of the arms of the government as well as the responsibilities of the government to the governed population. This paper seeks to discuss the constitution of the United States of American with respect to the powers of the arms of the government. The paper will look into the historical powers of the American presidency in comparison with the provision for separation of powers among the arms of the government. Controversy over Powers of the President The presidential powers in the United States of American have been surrounded with a lot of arguments with respect to whether or not such powers are consistent with the initial meaning as was provided for in the first amendment. The lack of agreement as to the consistency has led to a wide perception that the powers are being exercised with respect to convenience of solving emerging problems rather that according to the constitution. The executive branch of the government whose powers are vested in the president has in most cases been realized to overstep its mandate assuming the roles that were meant to be undertaken by the other arms, that is, the judiciary and the legislative arms. The powers of the president as was initially provided for were viewed to be limited with the only prerogative of approving legislations after such have been deliberated upon and passed by at least two-thirds of representatives from each of the house of the representatives. Powers of appointment of diplomatic representatives were also vested on the president subject to approval by the congress.

Even representations in international agreements such as treaties were subject to approval by the congress. Such provisions are however, not what Americans witness today with respect to the powers that are exercised by the president.

Prerogatives such as “foreign affairs powers, war powers, fiscal powers, legislative powers and administrative powers” (Kurland, 2006, p. 4) are currently identified as active roles of the executive contrary to the constitutional provisions. Powers Currently exercised by the President The increased authority that has been adapted by the presidency has been due to the direct of implied provisions that have been made by both the congress and the judiciary under the Supreme Court. The Supreme Court has, for instance, pronounced that the president, under precedence from the system in the Great Britain has the prerogative to appoint foreign diplomats. This has been contrary to the initial constitutional provisions. Foreign relations with respect to international agreements have also realized a deviation of powers from the original provisions. Treaties were originally supposed to be negotiated by the executive but approved by the congress on the basis of the two-thirds majority rule. In this setup, the congress had a basis to offer checks on the decisions of the executive. This has also been significantly altered by the Supreme Court through its decision that distinguished ex
