how can congress override a veto
1. Congress can override the President's veto if both houses (the Senate and the House of Representatives) vote to approve the bill by a â majority. However, this is rarely â¦done. 2. When there are not enough votes to have a majority, then bipartisanship occurs.
Congress, for example, passes laws. The president can check Congress by rejecting -- vetoing -- its legislation. This veto power is balanced, however, by the power of Congress to override the veto by a two-thirds vote of each house. The federal courts restrain Congress by ruling on the constitutionality of laws. This power of the judicial branch is balanced by the power of the president to appoint federal judges.
