Following their double victory in the November 4, 2026 midterm elections, securing control of both chambers of Congress, Democrats enter the new political landscape armed with a majority in the House of Representatives (requiring 218 seats, compared with the 212 they previously held) and another in the Senate.
This puts them in control of the full range of congressional investigative and oversight powers, while Trump remains in office until January 2029. (The Guardian, CBS)
What Are They Actually Preparing?
Not the “biggest trial in history,” as some media outlets exaggerate, but rather a coordinated campaign of investigations, hearings, and legislative oversight across several fronts. (NPR, Forbes)
1. The Epstein Files
An explicit priority.
Democrats are planning to investigate Trump’s dealings with Epstein and the Justice Department’s handling of the matter, particularly following last month’s (October) Judiciary Committee report.
In that report, ranking minority member Jamie Raskin cited “evidence from 11 women” contradicting Trump’s account that his relationship with Epstein ended before 2016.
Raskin described Trump’s version as
“not quite so.”
2. Businesses and Contracts
The investigations will target:
• Trump’s financial ventures, including Truth Social, cryptocurrencies, and overseas projects involving his children and foreign investors.
• Elon Musk’s contracts with the administration, including no-bid contracts and Pentagon server projects.
• Arms manufacturers and defense companies connected to the military.
3. The Mechanism: Subpoena Power
The essential authority here is the subpoena — the power to compel individuals and organizations to appear, provide testimony, and hand over documents.
Robert Garcia, the incoming chairman of the Oversight Committee, summarized the strategy in two words:
“Lawyer up.”

The Legal Dimension — And This Is What Matters
1. Can They Legally Prosecute Trump and His Family While He Is Still in Office?
• Congress does not itself act as a criminal court. Its role is to investigate, initiate impeachment proceedings, and refer cases to the Department of Justice or a special counsel.
Federal civil and criminal proceedings:
There is no established precedent for putting a sitting president on trial. The Justice Department, through its historic 1973 Office of Legal Counsel (OLC) memorandum, maintains that a sitting president cannot be brought before a criminal court. However, the courts have never definitively settled the issue.
Any indictment filed now would likely be challenged on immunity grounds and ultimately reach the Supreme Court — a historic precedent in every sense.
The more reliable route: Contempt of Congress.
If Trump, his son, Kushner, or Witkoff refuses to comply with congressional subpoenas, Congress has the authority to refer them directly for prosecution.
According to this analysis, that route remains open even while Trump is president and does not require anyone else’s approval.
2. What Good Is Trump’s Veto Power?
None in this context.
The presidential veto applies only to legislation under Article I, Section 7 of the Constitution.
It does not affect Congress’s oversight powers or its constitutional authority to hold officials accountable under Article I, Sections 2 and 3.
Trump cannot veto:
• A congressional hearing.
• A subpoena.
• An impeachment vote.
What he can do is delay proceedings, exert political pressure, and engage in legislative bargaining.
Any major Democratic bill would face an almost certain presidential veto, particularly because securing a 60-vote majority in the Senate would be nearly impossible.
For that reason, major legislation is unlikely to pass, and Democrats will concentrate on investigations.
3. Impeachment
• House of Representatives: Impeachment requires a simple majority, making it relatively easy for Democrats.
• Senate: Conviction requires 67 votes — a two-thirds majority — meaning support from at least 16 Republicans.
Historically, this has been an extremely high threshold, as demonstrated by the Clinton impeachment proceedings and Trump’s 2021 impeachment trial.
The more likely outcome is a House impeachment vote that sends a strong political message, alongside the possibility of imposing disqualification from future office through a simple-majority vote alone.
Strategic Conclusion
Democrats have effectively surrounded the executive branch during the final 18 months of Trump’s presidency, pursuing a dual mission:
First: Political accountability — covering financial dealings, Epstein, Musk, and corporate interests.
Second: Reasserting congressional authority over the White House. (The Guardian)
Pressure has already begun spreading into the Republican Party itself, with Republican officials urging Trump to change course following the electoral defeat. (Reuters)
But the most important development comes after January 20, 2029.
At that point, even these remaining barriers would fall, and the judicial process would become fully available to prosecutors — particularly after the Supreme Court’s 2024 ruling established partial presidential immunity that does not protect “ordinary acts.”
The Real Balance of Power
An investigation potentially unprecedented in its scale, but ultimately an instrument of congressional oversight, not an instrument of imprisonment — unless the administration complies with congressional subpoenas.
