In the United States, the President holds significant power when it comes to foreign policy making. However, the Congress also plays a crucial role in this area. While the Constitution gives the President the authority to negotiate treaties and make executive agreements, Congress has the power to restrain the President's foreign policy decisions through several checks and balances.

One way Congress can restrain the President in foreign policy making is through the power of the purse. Congress controls the budget and can choose to approve or deny funding for the President's initiatives or international agreements. By withholding funds or imposing conditions on their allocation, Congress can influence or restrict the President's foreign policy actions.

Additionally, Congress can exercise oversight over the President's foreign policy decisions. Through its various committees, Congress can investigate, hold hearings, and request information from the executive branch regarding foreign policy matters. This oversight function allows Congress to provide checks and balances on the President's actions and potentially influence or pressure the President to alter their foreign policy approach.

Furthermore, in certain situations, Congress can pass legislation that limits or constrains the President's authority in foreign policy. For example, Congress can pass laws that restrict the President's ability to engage in military actions or limit their ability to enter into certain types of international agreements. These laws can be enacted as checks on the President's authority and require their compliance.

It's important to note that the relationship between the President and Congress can vary, and there may be political factors and alliances that impact the extent to which Congress can restrain the President in foreign policy making. The balance of power between the branches of government is continually evolving, and specific situations may affect what actions Congress can take regarding foreign policy constraints.
