Final answer:
A presidential veto requires a two-thirds majority in both the House and the Senate to be overridden, not just a simple majority.
Step-by-step explanation:
False. If the president vetoes a bill, it does not require a simple majority in Congress to override the veto. Instead, a two-thirds majority in both the House of Representatives and the Senate is required for the bill to become law despite the presidential veto. This is a fundamental aspect of the system of checks and balances in the United States government that limits the power of the executive branch and ensures legislative authority.
If the president chooses to veto a bill, Congress has the ability to override this decision, making override of a presidential veto one of the key checks that the legislative branch has over the executive branch. However, achieving a two-thirds vote in both houses can be challenging, which makes a presidential veto a powerful tool.
