Indirect presidential veto is a term that refers to the president's ability to prevent a bill from becoming law without actually vetoing it. There are several other synonyms for this term that are commonly used. One such phrase is "pocket veto," which is when the president simply does not sign a bill within 10 days of receiving it while Congress is not in session. Another synonym is "passive veto," which describes instances when the president purposely delays the passage of a bill until it is too late to pass during the current session of Congress. Ultimately, these synonyms all refer to the same tactic used by the president to prevent a bill from becoming law without actually vetoing it.
