The Democrats' strong performance in the 2026 midterm elections could open the door to investigations into some of the most controversial aspects of Donald Trump's presidency. From immigration enforcement and family business interests to government contracts, political appointments and the use of presidential power, the next two years could bring a level of scrutiny that the White House has so far largely avoided.
The American midterm elections have produced a major political setback for Donald Trump and the Republican Party. The Democrats have secured control of the Senate and are close to taking the House of Representatives, potentially giving them control of both chambers of Congress.
For Trump, this presents a new challenge. He remains President and retains considerable executive authority, but the opposition could soon have the power to investigate his administration, demand documents, summon officials and examine decisions that have attracted considerable controversy.
Democratic politicians have already been preparing for this possibility. Their proposed investigations are not limited to immigration or the economy. They extend into the President's family business interests, government contracts, the Department of Justice, the treatment of political opponents and the conduct of federal agencies.
The question is whether these investigations will produce evidence of wrongdoing and meaningful changes, or simply become another chapter in America's increasingly bitter political divisions.
ICE: Immigration enforcement under scrutiny
One of the most immediate areas of interest is Immigration and Customs Enforcement, better known as ICE.
Trump made tougher immigration enforcement a central part of his political programme. ICE has consequently been given a prominent role in identifying, arresting and detaining people suspected of being in the United States illegally.
However, the methods used have attracted considerable criticism.
Democrats could investigate the treatment of detainees, deaths in immigration detention facilities, the use of force by enforcement officers and cases involving people who are legally entitled to remain in the United States.
There are also questions about the contracts awarded to private companies operating detention facilities.
When public money is used to pay private contractors to house and manage immigration detainees, there is an obvious need to establish whether contracts are properly awarded, whether costs represent value for money and whether companies are meeting their obligations.
There is a wider question too. If immigration enforcement becomes a substantial commercial business, are the interests of private contractors always aligned with the public interest?
Congress could examine these arrangements and investigate whether political connections have influenced the awarding of contracts. Allegations of improper influence would need to be established through evidence rather than assumed.
Corruption and the President's family business interests
Perhaps the most politically sensitive investigations could concern the financial interests of Trump and members of his family.
Democrats have already indicated that they want to examine how the President's family business interests have developed during his second term.
Questions have been raised about cryptocurrency ventures, foreign investments, business relationships and the activities of companies connected to members of the Trump family.
One particular area of interest is the relationship between Donald Trump Jr's investment business and companies that may also have dealings with the federal government.
There are also questions surrounding Jared Kushner, Trump's son-in-law, whose private investment activities and international financial relationships have attracted congressional attention.
The issue is not simply whether members of a presidential family are allowed to conduct business. It is whether government decisions could create financial advantages for people connected to the President.
A company receiving a government contract is not evidence of corruption. Nor is a foreign investment in itself proof of improper influence.
But where public policy, private financial interests and political relationships overlap, transparency becomes particularly important.
Democrats could use congressional investigations to demand financial records, examine business relationships and establish whether any conflicts of interest or improper arrangements exist.
The Department of Justice and FBI
Another important area concerns the independence of America's law enforcement institutions.
The Department of Justice and the FBI are expected to operate according to the law rather than the political interests of whichever party occupies the White House.
There have been concerns about the dismissal of officials, changes in senior appointments and investigations involving people who have publicly opposed Trump.
Democrats could examine whether prosecutorial decisions have been influenced by political considerations and whether government agencies have been used unfairly against political opponents.
They could also investigate whether experienced officials have been removed because their findings or advice were inconvenient to the administration.
This is an issue that extends beyond Trump and the Democrats.
A democracy depends on public confidence that the police, prosecutors and investigators apply the law consistently, regardless of political connections.
If that confidence is damaged, rebuilding it could take years.
The Epstein files and unanswered questions
The handling of records relating to Jeffrey Epstein could also return to the centre of congressional attention.
The Epstein scandal involved the sexual exploitation and trafficking of underage girls, with serious questions about how he was able to maintain relationships with wealthy and influential people for so long.
The release of government records has generated considerable controversy, including questions about missing material, redactions and the protection of victims' identities.
Democrats could investigate whether the Department of Justice has complied fully with its disclosure obligations and whether the authorities have provided an adequate explanation of their handling of the case.
There is a particular need to distinguish between people who appear in documents, people who associated with Epstein and anyone against whom there is actual evidence of criminal conduct.
Being mentioned in a document or having known Epstein does not establish involvement in his crimes.
The public nevertheless has a legitimate interest in understanding whether wealthy and influential individuals received preferential treatment and whether the authorities failed to act when they had information about criminal activity.
Government contracts and the influence of wealthy businesses
The relationship between political power and large corporations could become another major investigative subject.
The American government spends enormous sums on defence, technology, construction, immigration enforcement and other services.
Many of these activities are carried out by private companies through government contracts.
Democrats could examine whether contracts have been awarded fairly, whether political donors have received favourable treatment and whether businesses connected to political figures have benefited from government decisions.
The defence industry deserves particular attention.
Military spending is already enormous, and the conflict with Iran could generate additional demands for aircraft, missiles, ammunition and other equipment.
Congress has a responsibility to establish where this money goes and whether taxpayers are receiving value for it.
These investigations could also examine the relationship between major technology companies and the administration, particularly where government contracts, regulation and political influence overlap.
The wider question is whether access to political power is becoming an increasingly valuable commercial asset.
The civil service and the removal of experienced officials
Trump's approach to the federal workforce could also receive greater scrutiny.
Government departments employ people with specialist knowledge and experience in areas ranging from taxation and public health to scientific research, education, environmental protection and national security.
Changes to government structures and the removal of large numbers of employees may be presented as an exercise in reducing bureaucracy and saving taxpayers' money.
But reducing staff numbers does not automatically make government more efficient.
Democrats could investigate whether experienced employees have been dismissed unfairly, whether important services have been weakened and whether departmental responsibilities established by Congress are still being fulfilled.
There is a practical question here that should interest taxpayers of either political persuasion.
If a government department loses experienced people, does the saving in wages outweigh the cost of mistakes, delays, lost expertise and the need to employ expensive outside consultants?
That is something which should be measured rather than simply asserted.
The war with Iran and the use of presidential power
The conflict with Iran adds another important dimension to the investigations Democrats could pursue.
Congress could demand information about the intelligence used to justify military action, the objectives of the operation, its financial cost and the administration's plans for bringing the conflict to an end.
There are also questions about whether Congress was properly informed and whether the President has exceeded the authority available to him under the Constitution and the War Powers Resolution.
A Democratic-controlled Congress could seek to restrict funding for particular military operations or introduce legislation requiring greater congressional approval.
However, Trump remains Commander-in-Chief. Congress cannot simply take over the military chain of command.
The disagreement could therefore develop into a major constitutional and political confrontation.
Can the investigations actually change anything?
There is a difference between having the power to investigate and having the power to force change.
Congressional committees can request documents, issue subpoenas and summon witnesses. They can also hold public hearings and refer evidence of suspected criminal conduct to the appropriate authorities.
But the White House can resist requests, invoke executive privilege and challenge subpoenas in court.
Legal disputes can take months or even years to resolve.
There is also the danger that investigations become so politically partisan that the public loses confidence in their findings.
Democrats will need to demonstrate that they are interested in establishing facts rather than simply finding reasons to attack the President.
The Senate result gives them an additional opportunity to scrutinise presidential appointments, including senior officials and federal judges. The extent of their ability to block appointments will depend on the particular circumstances and Senate procedures.
If Democrats also secure the House, their investigative powers will become considerably more extensive.
A test of American democracy
The next two years could be an important test of the American system of checks and balances.
The President has considerable powers, but those powers are not unlimited. Congress controls legislation and public spending, while the courts have a role in determining whether government actions comply with the law.
The midterm elections have given Democrats a stronger position from which to challenge the administration. But their success will ultimately be judged by what they establish and what changes follow.
There is a wider issue that goes beyond the personalities of Donald Trump and his political opponents.
In any democracy, voters need confidence that government contracts are awarded fairly, public money is properly accounted for, law enforcement is independent and those holding political office cannot use their positions for personal advantage.
These are not exclusively Democratic or Republican concerns. They are basic requirements of responsible government.
Trump will remain in the White House, but the political protection he has enjoyed from a Republican-controlled Congress may now be coming to an end.
The public will be watching to see whether the new congressional majority can turn its electoral success into effective scrutiny and genuine accountability.
Winning an election gives politicians the right to ask difficult questions. It does not automatically provide the answers.
