Presidential veto powers function as a critical check within the political process, allowing the president to reject legislation passed by Congress. This power is a critical part of the system of checks and balances designed to prevent any one branch of government from becoming too powerful. However, Congress may override a veto with a two-thirds majority vote in both houses. Thus, veto powers can influence legislative agendas, encouraging bipartisanship and negotiation while also reflecting the president's priorities and vision for national policy.
