Once the President vetoes a bill that originated in the House of Representatives, the bill returns to the House with a veto message from the President explaining their objections. The House then has the opportunity to reconsider the bill. If two-thirds of the members present and voting still support the bill, the bill is sent to the Senate. The bill is also reviewed in the Senate, and if two-thirds of the members present and voting support the bill, it becomes law despite the President's veto. This process of overriding a presidential veto ensures that a substantial majority in both chambers of Congress truly supports the legislation, underlining the system of checks and balances among the different branches of government. Throughout this process, the members of Congress may engage in debates and discussions, potentially amending the bill to address the President's concerns in hopes of earning their approval or garnering more support from fellow legislators to override the veto.
