When the President nominates an individual to serve as Secretary of State, the Senate must confirm that appointment. Which constitutional principle does this illustrate?

Checks and Balances

Explanation:

The Checks and Balances system implies that governmental power is controlled by governmental power itself, based on a separation of powers. This means that all the political power of a government in a country is divided into three spheres called Executive, Legislative and Judiciary, where each has its role and one must inspect and analyze the choices made by the others, thus generating political security. An example of this can be seen when the senate must approve the nomination of the president for the position of secretary of state.
