WASHINGTON – The political landscape in United States witnessed dramatic shift amid midterm elections, raising two questions that could shape remainder of Donald Trump’s presidency and people are wondering whether Democrats use their congressional majority to impeach President, and do they have enough power to bring America’s war against Iran to an end?
Democratic victories in House of Representatives and Senate set stage for confrontation between Congress and White House, potentially exposing Trump administration to investigations, legislative challenges and restrictions on military spending.
Although the new balance of power could dent Trump’s influence over legislation, Democrats would still face major constitutional obstacles in attempting to remove him from office or compel an immediate end to military operations against Iran.
November 3 midterm elections reportedly delivered substantial gains for Democrats, with the party crossing the 218-seat threshold required to control the House of Representatives and securing an estimated 54 Senate seats, including independents aligned with Democrats.
The reported results show gains in traditionally Republican states, with voter concerns over economic pressures, rising living costs and the consequences of the Iran conflict. Control of both chambers would allow Democrats to determine congressional priorities, lead powerful committees, investigate administration decisions and challenge government spending proposals.
Could Democrats Impeach Trump for Third Time?
The possibility of another impeachment has emerged as one of the most significant political questions following the elections. Under US Constitution, the House of Representatives has the authority to impeach a sitting president through a simple majority vote.
If all 435 members participate, 218 votes are required to approve articles of impeachment. A Democratic majority would therefore make it possible to initiate impeachment proceedings without Republican support, provided enough Democratic lawmakers agree to pursue them.
Congressional investigations could examine the administration’s handling of the Iran conflict, financial matters, foreign policy decisions and other actions considered potential grounds for impeachment. However, impeachment would require more than political disagreements. Lawmakers would need to establish a basis for formal charges and secure majority support in the House.
Trump already been impeached twice, in 2019 and 2021, making another attempt an unprecedented third impeachment of the same American president. Both previous proceedings ended in Senate acquittals, allowing him to remain in office.
Removing Trump to be Harder
Even if Democrats approve impeachment charges in the House, that would not automatically remove Trump from the presidency. Senate must hold a trial, and conviction requires a two-thirds majority of senators present.
With all 100 senators voting, at least 67 votes would be necessary to convict and remove the president. If Democrats and their aligned independents hold approximately 54 seats, they would need at least 13 additional senators to support conviction.
That means a successful removal would require substantial Republican cooperation. Without such support, the House could impeach Trump while the Senate ultimately acquits him, as happened during his previous presidency. Democratic majority could therefore increase the possibility of impeachment proceedings without guaranteeing Trump’s removal.
Iran War Aspect
Beyond impeachment, Democrats’ reported election gains raised questions about the future of America’s military campaign against Iran. The conflict started with joint US-Israeli strikes in February 2026 and has generated growing concerns about military expenditure, international energy prices, regional stability and the consequences for American taxpayers.
Although Trump presented campaign as largely successful, continuing tensions and military operations have kept the conflict at the centre of Washington’s political debate. Democrats could use their congressional majorities to challenge administration’s military strategy, demand explanations for continued operations and attempt to restrict funding.
However, Congress does not directly command American military forces. The president retains his constitutional role as Commander-in-Chief, making an immediate congressional order to end the conflict legally and politically complicated.
One major option available to Democrats is War Powers Resolution of 1973, which was enacted to limit prolonged American military involvement in hostilities without congressional authorization. Under this legislation, certain unauthorized military engagements are generally subject to a 60-day termination requirement, with a possible additional 30 days for withdrawal.
Congress can also pursue legislation directing the withdrawal of American forces from hostilities. Although original law includes a mechanism involving concurrent resolutions that do not require presidential approval, its constitutional enforceability has been disputed.
A binding withdrawal measure passed as ordinary legislation could face Trump’s veto, making bipartisan support essential if Congress attempted to override him. Consequently, even a successful congressional vote demanding withdrawal might not immediately end American operations against Iran.
One of Congress’s strongest constitutional powers is its control over federal spending. Democrats could attempt to use that authority to limit the financial resources available for further military operations against Iran.
They could introduce restrictions in defence spending legislation, oppose additional military funding or impose conditions on how appropriated funds are used. Such measures could increase pressure on the White House, particularly if the conflict continues to require substantial military expenditure.

Congress used funding restrictions to influence American involvement in overseas conflicts, including during the Vietnam War. However, the administration could resist these efforts through negotiations, legal arguments or presidential vetoes. Previously approved funding and existing executive powers could also complicate attempts to halt operations immediately.
Trump Could Face Probe Over Iran Conflict
Democratic takeover could also expose senior administration officials to more extensive congressional scrutiny. Democratic-controlled committees could investigate the legality of military operations, the financial cost of the conflict, civilian casualties, military objectives and the administration’s diplomatic strategy.
Senior officials, including Defense Secretary Pete Hegseth, could be called before congressional hearings to explain decisions surrounding the campaign. Lawmakers could also demand government records, military assessments and testimony from officials involved in shaping American policy toward Iran.
Such investigations could increase public pressure on the administration and influence future legislation. However, investigations alone would not force the president to withdraw American troops or establish grounds for impeachment.
Trump’s Veto Still Obstacle
Despite Democrats’ gains in House, Trump retains the authority to reject legislation passed by Congress. Overriding a presidential veto requires a two-thirds majority in both the House and Senate.
Assuming full participation, Democrats would need 290 votes in the House and 67 in the Senate to override a veto. Their projected majorities fall short of those thresholds. This means Republicans could continue to play a decisive role in determining whether legislation restricting the Iran conflict becomes law.
The same numerical challenge applies to impeachment, where a Senate conviction would require significant Republican support. Therefore, Democrats could pass legislation challenging Trump’s policies but still struggle to enforce major restrictions without broader bipartisan agreement.
The next phase of the political struggle is expected to begin when the newly elected Congress takes office on January 3, 2027. Democrats could move to launch investigations, review military expenditure, challenge administration decisions and consider legislative restrictions on the Iran campaign.
They may also face pressure from within their own party to pursue impeachment proceedings against Trump. However, Democratic leaders would have to weigh those demands against other priorities, including inflation, government spending, economic policy and national security.
