Final answer:
All the options listed—the power of veto, the power to convene Congress, and the power to communicate directly with Congress—are legislative powers of the president. These powers allow the President to influence legislation and work with Congress to address national issues.
Step-by-step explanation:
The question asks about the legislative powers of the President of the United States. Among the powers of the president, they indeed have the authority to veto bills, the power to convene Congress for special sessions, and the ability to communicate directly with Congress, such as in the annual State of the Union address. Hence, the correct answer is that all of these are legislative powers of the president.
Specifically, the President can sign a bill into law or veto it, returning it to Congress with a veto message. A veto can be overridden by Congress. Additionally, the President can perform a pocket veto if Congress adjourns within ten days of sending the bill and he does not sign it. The President can also issue signing statements that express their opinions on the constitutionality of provisions within a bill.
Furthermore, the Constitution empowers the President to require written opinions from their Cabinet members, convene Congress on 'extraordinary occasions,' and pardon individuals for offenses against the United States, among other powers. In terms of foreign policy powers, the President shares these with Congress, reflecting a system of checks and balances.
