Final answer:
Chapter activities are not determined strictly by the President or select members. The President has significant influence but the Constitution requires involvement from the Senate in treaty ratification and nominations, and the President shares foreign policy powers with Congress. The House of Representatives can also initiate impeachment proceedings against civil officers, including the President.
Step-by-step explanation:
The determination of a chapter's activities is not solely at the discretion of the President or a few select members. While the President has significant power, the Constitution requires a more collaborative approach for certain actions. For instance, although the President serves as the Commander in Chief of the United States armed forces and can propose treaties, the Senate is involved in the ratification of treaties and confirmation of nominations. Specifically, the Senate must approve treaties by a two-thirds vote and also confirm nominations made by the President for positions such as judges and other civil officers.
With regard to foreign policy, the President and Congress share power, indicating that a single individual does not unilaterally decide on all policies and activities. The President is indeed a central figure in foreign policy-making, but Congress has significant powers too, including the power to declare war and control the budget, which can affect foreign policy decisions.
Additionally, the Constitution specifies that the House of Representatives has the unique authority to instigate impeachment proceedings against the President, a Vice President, or other civil officers for 'Treason, Bribery or other high Crimes and Misdemeanors.' Although the President has considerable executive dominance, this is checked by legislative powers and procedures as outlined in the Constitution.
