With a two-thirds majority in both houses.

To override a presidential veto of a bill, Congress must follow these steps:

1. The bill must pass through both the House of Representatives and the Senate with a simple majority vote in each chamber (51% or more).

2. Once the bill has been passed by Congress, it is sent to the President.

3. The President then has the option to either sign the bill into law or veto it.

4. If the President chooses to veto the bill, it is returned to Congress with an explanation for the veto.

5. To override the veto, Congress must vote on the bill again. This time, it requires a two-thirds majority vote in both the House and the Senate (67% or more) for the bill to become law, despite the President's veto.

Therefore, the correct answer is: With a two-thirds majority in both houses.
