Final answer:
Congress can pass the legislation by overriding the president's veto with a two-thirds majority vote.
Step-by-step explanation:
If a president vetoes a bill, Congress can still pass the legislation by overriding the president's veto. This requires a two-thirds majority vote in both the House of Representatives and the Senate. Once the bill is vetoed, it is returned to Congress, and if the necessary majority is achieved, the bill becomes law without the president's approval.
