Why Capitol Hill Holds More Powers Than You Think

With the 2024 election behind us, Americans are shifting their focus from the campaign trail to the halls of Congress, where newly elected representatives will shape the future of our nation. The U.S. Congress—the legislative branch of our federal government—plays a pivotal role in creating laws, regulating policies, and overseeing government activities. But how exactly does Congress work, and why is it so vital to our everyday lives?

Every two years, Congress reorganizes itself as new members are sworn in, committees are restructured, and legislative priorities are set. The 119th Congress will convene on January 3, 2025, creating an opportune time to understand its powers, duties, and functions. 

Understanding the role of Congress empowers you to make a lasting impact, long after Election Day, whether you are a first-time voter or a seasoned participant in the public process. By learning about Congress’s role, you can hold elected officials accountable and stay engaged as an informed citizen. 

The Powers of the U.S. Congress in Washington, D.C.

The U.S. Congress, outlined in the Constitution, holds significant powers, often known as “enumerated powers,” which are essential to the checks and balances that keep the U.S. government from concentrating too much authority in any one federal agency.

The Power to Make Laws

Congress’s most important role is its power to make laws. This authority allows Congress to create, amend, and repeal laws across various issues affecting our daily lives, from healthcare and education to national security and the economy. This duty involves extensive research, collaboration, and debate to create effective and equitable policies.

Legislation typically begins in the House or Senate, is debated, amended, and later voted on. If both chambers pass the bill, it goes to the president, who can either sign it into law or veto it. This process illustrates Congress’s role in ensuring the democratic creation of laws and underscores the importance of the legislative branch in government.

The Power to Regulate Commerce

Another critical power of Congress is the ability to regulate commerce, which includes both interstate and foreign trade. This authority has allowed Congress to address issues including but not limited to trade tariffs, labor standards, and consumer protections. For example, Congress can pass laws that regulate the food and drug industries, protect workers’ rights, and prevent monopolistic practices.

This power has expanded over time, particularly as new industries have emerged. Today, Congress oversees internet commerce and cybersecurity, highlighting the legislative branch’s ability to adapt to changing economic and social landscapes.

The Power to Tax & Spend

Congress levies taxes and allocates federal spending to fund government operations and provide public services. The “power of the purse” is one of Congress’s most significant tools, allowing it to influence nearly every government service. The budget and appropriations process determines how much funding federal agencies receive, impacting areas like defense, healthcare, education, and infrastructure.

Through this power, Congress can support programs for the public good, such as Social Security, Medicare, and national defense. It can also address economic crises, such as the 2008 Great Recession and the COVID-19 pandemic, by passing emergency relief packages to assist individuals, businesses, and local governments.

The Power to Declare War

While the president is the armed forces commander-in-chief, only Congress has the official capacity to declare war. This power is a critical check on the executive branch, ensuring that military actions receive approval from representatives of the people. Congress has formally declared war five times in U.S. history, though it has authorized the use of military force on numerous other occasions.

The requirement for congressional approval acts as a safeguard, encouraging deliberation and accountability in decisions involving armed conflict.

Oversight and Investigative Powers

Congress also has broad oversight and investigative powers, allowing it to monitor the executive branch’s policies, federal agencies, and even private organizations. The U.S. government was built on a system of checks and balances, and Congress played a central role in maintaining this balance. These powers ensure that government operations remain transparent, lawful, and accountable to the public.

The government can investigate issues ranging from financial fraud to public health emergencies in congressional committees. For example, these investigative hearings have examined corporate misconduct, environmental disasters, and, more recently, the handling of the COVID-19 response. Such investigations highlight Congress’s duty to uphold justice and protect the interests of the American people.

Importance of the U.S. Congress in Government

Understanding the legislative branch is essential to grasping why Congress matters. Congress is the direct link between the people and the federal government. By representing the diverse voices of Americans, it creates a government that reflects the country’s values, needs, and ambitions.

Why Congress Matters to You

While it might seem like Washington is far removed from our daily lives, Congress’s decisions impact everything from the air we breathe to the safety of our food, the structure of our healthcare, and the security of our nation. 

One of Congress’s primary duties is to represent the interests of the American people. Senators and representatives are the voices of our states and districts, ensuring that our needs, concerns, and values are considered in national legislation. The laws Congress passes shape our economy, protect our rights, and provide essential public services that benefit all Americans.

Congress members also serve their constituents by addressing individual issues, guiding federal programs, and offering support in navigating federal agencies. For example, a Congress member’s regional office might help a local veteran receive benefits, assist a family facing immigration challenges, or provide updates on Social Security claims.

Ensuring Accountability

Through its oversight functions, Congress ensures that federal agencies operate transparently and efficiently, serving the public’s best interest. This accountability is crucial in a democratic government, where officials must answer to the people who elect them.

Promoting Civic Engagement

Finally, an informed understanding of Congress and its duties can lead to greater civic engagement. When citizens understand the legislative branch’s purpose and powers, they are more likely to vote, participate in public discourse, and hold their elected officials accountable. This engagement strengthens democracy and fosters a government representing the people’s will.

Key Legislative Bills Set to Shape Congress in 2025 and Beyond

As we look to Congress’s upcoming sessions, several major legislative issues are poised to dominate its agenda. These issues require bipartisan attention and impact the economy, environment, healthcare, and fiscal policies.

Tax Cuts and Jobs Act (TCJA) Expirations

The TCJA of 2017 lowered tax rates for individuals and businesses, stimulating economic growth. However, several provisions—including individual tax cuts and the child tax credit—are set to expire in 2025. Congress will face a crucial decision on whether to extend these cuts, modify them, or let them expire. This decision will impact household finances, the national budget, and future deficit projections​.

Debt Limit and Fiscal Responsibility

With the Fiscal Responsibility Act temporarily addressing the debt ceiling crisis, Congress must revisit the debt limit in 2025. Lawmakers will likely engage in heated debates about budget cuts or revenue increases to address the rising national debt. Given that the national debt is projected to surpass 100 percent of GDP by 2025, these discussions are vital for sustainable fiscal management​.

Climate Policy and Renewable Energy Initiatives

The climate crisis has become a central issue for Congress, with past legislation such as the Inflation Reduction Act setting a foundation for renewable energy development and emission reductions. Future climate policy may include expanding green tax credits, incentivizing renewable energy production, and addressing long-term environmental goals. These discussions will affect energy policy, transportation, and agriculture as Congress seeks alternative and sustainable solutions​.

Conclusion

Understanding the purpose and functions of the U.S. Congress is vital to being an informed and engaged citizen. By recognizing its powers and roles in government, we gain a deeper appreciation for how democracy operates—and our part in shaping it.

Remember, members of Congress represent you and your community’s needs and priorities.
