If the president vetoes a bill, Congress can still make it law by passing it again with:

1. Congress makes law, but that power is checked by the president, who can veto proposed legislation. 2. A vetoed bill returns to Congress to be voted on again. 3. If it then passes both the House of Representatives and the Senate with a two-thirds vote in its favour, it becomes law even though the president refused to sign it. 4. The chapter notes that because each branch knows the other's powers, Congress often drafts bills addressing the president's concerns in advance, and presidents use the veto sparingly. _Source: OpenStax American Government 3e (CC BY 4.0), Ch 2 "The Constitution and Its Origins", §2.3 The Development of the Constitution_
