During which process does the Executive Office of the President (EOP) primarily interact with Congress?

The Executive Office of the President (EOP) primarily interacts with Congress during the budget preparation and negotiation process. This is because the EOP, particularly through the Office of Management and Budget (OMB), plays a crucial role in developing the President’s budget proposal, which is then submitted to Congress. This process entails outlining the administration's funding priorities and policy goals, requiring extensive negotiations with various congressional committees.

Additionally, Congress holds significant power over the budget, as it must review, amend, and ultimately approve the proposed budget. This interaction emphasizes the critical partnership and sometimes contention between the executive and legislative branches regarding fiscal policy and governance.

While the other processes listed involve some degree of interaction with Congress, they do not typically require the same level of ongoing negotiation or collaboration throughout a season, as seen with the budget process. Judicial nominations and international treaties often involve less frequent communication, and impeachment proceedings are more reactive and centered on specific circumstances rather than a continuous legislative process like budgeting.
