Which best explains how the senate affects the powers of the president

The Senate must approve many presidential actions.

Explanation:

The president is responsible for the appointment of several members of the executive branch. Ambassadors, members of the Cabinet and other federal officials, are all appointed by the president with the "advice and consent" of a Senate majority. Appointments made while the Senate is not in session are temporary and expire at the end of the next session of the Senate.

The president is also at the forefront of foreign policy. Through the Department of State and the Department of Defense, the president is responsible for the protection of Americans abroad and foreign citizens in the United States. The president decides whether to recognize new nations and new governments and negotiates treaties with other nations, which become effective in the United States when they are approved by two-thirds of the Senate. The president can also negotiate "executive agreements" with foreign powers that are not subject to Senate confirmation.

The president also has the power to propose federal judges, including members of the United States Supreme Court and the Courts of Appeals. However, these appointments require confirmation from the Senate and this can be an important obstacle to the possibility that a president would like to form a federal judiciary with a particular ideological stance.

the us constitution is a living document, meaning that it can be changed over time as the country changes.
