Veto, Whilst the legislative branch proposes the bulk of US federal legislation, all laws must be signed by the president and the president may veto and prevent a bill becoming law. For example, Congress passed a resolution that rejected Trumps national emergency, this got vetod by Trump.
However, similerarly to a Executive Order it can be overturned by a two-thirds majority, For example one of President Obama’s vetoes was overridden – this was after he vetoed a bill that would have allowed the families of 9/11 victims to sue Saudi Arabia.
