Answer:
Congress can override a presidential veto by following these steps:
1. The bill must first be passed by both the House of Representatives and the Senate with a two-thirds majority vote in each chamber. This is a higher threshold than the usual majority required to pass a bill.
2. Once the bill has passed with a two-thirds majority in both chambers, it is then sent to the president for approval or veto.
3. If the president chooses to veto the bill, they must provide a written explanation for the veto. The bill is then returned to the chamber in which it originated (either the House or the Senate).
4. In order to override the veto, the chamber that received the vetoed bill must hold a vote to reconsider it. A two-thirds majority vote is required in this chamber to proceed with overriding the veto.
5. If the chamber that received the vetoed bill successfully reaches a two-thirds majority vote to override the veto, the bill is sent to the other chamber (if it hasn't already voted on it) for a similar vote. Again, a two-thirds majority is needed to override the veto in the second chamber.
6. If both chambers achieve a two-thirds majority vote to override the veto, the bill becomes law, regardless of the president's objections.
It's important to note that overriding a presidential veto is a challenging process and requires significant support from both the House of Representatives and the Senate. This system of checks and balances ensures that the power of the executive branch is balanced by the legislative branch.
