The midterm election results have raised the possibility that President Donald Trump could face a Congress controlled by Democrats beginning next year. However, their sweeping victory does not necessarily mean they will have a free hand to advance their legislative agenda.
Trump has indicated that he could use his presidential veto power to block bills that challenge his administration’s policies. Democrats are expected to push legislation aimed at reversing some of Trump’s policies while using their new congressional majority to investigate his administration.

In a Truth Social post, Trump shared a photograph of a red baseball cap bearing the word “VETO.” Although he later acknowledged the Democrats’ victory, he initially warned, “If we didn’t win, I veto everything.”
The U.S. Constitution states that every bill passed by the House of Representatives and the Senate must be presented to the president before becoming law. The president, however, can reject legislation passed by Congress by exercising the veto power granted under Article I, Section 7 of the Constitution.
Generally, the president has 10 days, excluding Sundays, to sign a bill, return it to Congress with objections or allow it to become law without a signature, provided Congress remains in session.
A regular presidential veto sends the legislation back to the chamber where it originated, along with an explanation of the president’s objections. Congress can override the veto if two-thirds of lawmakers in both chambers vote in favor of doing so. This requires 290 votes in the House of Representatives and 67 in the Senate, making a veto difficult to overturn.
Trump can also use a pocket veto. If the president does not sign a bill within the 10-day period and Congress adjourns in a way that prevents its return, the bill does not become law. Lawmakers would have to reintroduce the proposal and repeat the legislative process.
During his first term, Trump vetoed more than 10 bills.

The threat of a veto can also influence legislation before it reaches the president’s desk. The White House can communicate its position through Statements of Administration Policy, warning lawmakers that the president may reject a particular bill.
Despite these constraints on legislation, control of Congress gives Democrats several ways to challenge the Trump administration. They can launch investigations, summon administration officials, issue subpoenas and examine federal spending and government policies. Congressional committees can also hold hearings that subject decisions made by the Trump administration to greater scrutiny.
