What are the three parts of the executive branch? which president used the slogan “the buck stops here”? what does it mean?

The three parts of the executive power are: the President, who is the head of the government as well as the armed forces. According to the constitution he is the guarantor of the application of the laws. Among its executive powers, it can enact executive orders, which have legal validity for federal bodies. The Vice President is the second office of the government and in case of death, resignation, destruction or serious impediments takes the place of the President. This fact has happened only nine times in American history. He is the president of the Senate and has the power to resolve any disputes with his vote. The Cabinet of Government is made up of 15 departments nominated by the President and the Senate which must be confirmed and / or rejected by a simple majority vote. The members of the Cabinet are responsible for directing departments (also called ministries) including those of Justice and the Department of Defense.

The president who used the slogan "The dollar stops here" is Harry S.Truman. Truman was born in 1884 and died in 1972 and was both vice president and 33 president of the United States of America from 1945 to 1953 under the Democratic party. Truman remembers especially for the atomic bombing on Hiroshima and Nagasaki at the end of the 2nd world war, the cold war with Russia and the Korean war, and the war in Vietnam.

The saying "the dollar stops here" comes from the slang expression "pass the time", meaning how to pass the responsibility. President Truman understood it as "the decision must be taken" in the sense that nothing but the president (whoever he is) must make the decisions! So this slogan symbolizes the heavy responsibility that weighs on the shoulders of the President and by extension of all those people who have executive power in the nation.
