3.3.2 – Informal sources of presidential power and their use
3.2.2 – The functions of Congress
Marco Rubio’s appearance before the Senate Foreign Relations Committee highlighted the tension between executive action in foreign policy and congressional scrutiny. Questioned on the administration’s recent approach to Venezuela, the Secretary of State set out a confident defence of US policy while being repeatedly pressed on how decisions had been made and who had been informed.
Rubio stressed that the United States was not entering a wider conflict. He presented the administration’s actions as limited and strategic, aimed at stabilising Venezuela and creating the conditions for democratic change rather than pursuing long-term military involvement. He also emphasised that any use of force was tightly constrained and framed around national security concerns. Despite these assurances, much of the hearing focused on transparency. Senators from both parties questioned whether Congress had been properly briefed before key actions were taken. Concerns were raised about the legal basis for decisions, access to intelligence, and whether the executive had moved too quickly without meaningful consultation with lawmakers. These exchanges revealed unease about the balance of power in foreign policy, where presidents often act first and explain later.
The hearing ranged beyond Venezuela, touching on other global issues, which underlined how Senate committees use testimony to assess the wider direction of foreign policy, not just individual crises. Rubio’s responses were careful, defending executive discretion while acknowledging Congress’s right to ask difficult questions.
Overall, the session demonstrated how congressional oversight works in practice. While Congress cannot directly control day-to-day foreign policy, hearings force senior officials to justify their actions publicly. This scrutiny acts as a check on executive power, reinforcing accountability even when the presidency dominates foreign affairs.
