Who has the authority to sign bills so they can become laws?

The authority to sign bills so they can become laws lies with the President. In the legislative process, after both the House of Representatives and the Senate have passed a bill, it is sent to the President for approval. The President has the power to either sign the bill into law or veto it. If the President signs the bill, it becomes law and is enforced, illustrating the executive's role in the legislative process.

Other roles, such as the Speaker of the House, Senate Majority Leader, and Chief Justice, play important functions in their respective areas but do not have the authority to sign bills into law. The Speaker of the House presides over House proceedings, the Senate Majority Leader guides legislative priorities in the Senate, and the Chief Justice heads the judicial branch, interpreting laws but not involved in the legislative process of signing bills.
