How can the President check the power of Congress?

The ability of the President to veto legislation serves as a crucial check on the power of Congress. When Congress passes a bill, it is sent to the President for approval. If the President believes the legislation is not in the country’s best interest or conflicts with their policy objectives, they can exercise the veto power, rejecting the bill. This action prevents the bill from becoming law unless Congress can override the veto with a two-thirds majority in both houses.

The veto power is an essential part of the system of checks and balances established by the Constitution, ensuring that no single branch of government becomes too powerful. This mechanism encourages cooperation between the executive and legislative branches, as Congress must consider the President's perspective when drafting legislation.

In contrast to the veto, the other options reflect different functions and powers. Proposing amendments is primarily a legislative process and involves both Congress and the states. Calling Congress into session is a presidential function, but it does not directly check legislative power. Confirming appointments pertains to the executive's role in the judicial or executive branches, where the Senate has a significant say, but does not directly check legislative authority as the veto does.
