Ten years ago, Donald Trump made one of the most extraordinary economic promises of his first presidential campaign.

The United States was carrying roughly $19 trillion in national debt.

Trump said he could get rid of it.

Not reduce the deficit.

Not slow the growth of the debt.

Get rid of the debt.

Asked during a 2016 Washington Post interview how quickly he could accomplish that, Trump said he believed it could be done over eight years.

Those eight years have come and gone.

The national debt is not zero.

It is now more than $40 trillion.

MORE THAN DOUBLE

The United States officially crossed the $40 trillion threshold in August 2026, according to Treasury Department data.

That means the federal debt has more than doubled from the roughly $19.9 trillion outstanding when Trump first took office in January 2017.

The comparison is striking because eliminating the debt was not some vague campaign slogan.

Trump was specifically asked how long eliminating approximately $19 trillion would take.

His answer: eight years.

When interviewer Bob Woodward pointed out that accomplishing that would effectively require eliminating trillions of dollars in debt every year, Trump argued that better trade deals would help make it possible.

That never happened.

Instead, the debt continued climbing.

TRUMP DIDN'T CREATE $40 TRILLION IN DEBT

There is an important distinction.

Donald Trump did not personally create $40 trillion in federal debt.

The national debt is the accumulation of decades of federal borrowing under Republican and Democratic presidents and Congresses.

Joe Biden presided over substantial additional borrowing during his presidency. Both administrations also confronted the extraordinary expenses associated with the COVID-19 pandemic, when Congress authorized enormous emergency spending programs.

Social Security, Medicare, Medicaid, defense spending, tax policy and other long-term structural issues have also contributed to persistent federal deficits.

But none of that changes the comparison between Trump's promise and what actually happened.

He said the debt could be eliminated.

During his first presidency, it increased substantially instead.

And after returning to the White House, Trump has continued governing a country running enormous annual deficits.

THE FIRST TRUMP TERM

When Trump took office in January 2017, the national debt stood at approximately $19.9 trillion.

When he left office in January 2021, it was roughly $27.8 trillion.

That was an increase of nearly $8 trillion.

COVID-19 accounts for a significant portion of that increase, as Congress and the Trump administration approved trillions of dollars in emergency spending during the pandemic.

But deficits were already increasing before COVID arrived.

Trump also signed the Tax Cuts and Jobs Act of 2017, which substantially reduced federal tax revenue relative to what otherwise would have been collected.

The administration argued that stronger economic growth would help offset the reductions.

The federal budget never came close to balancing.

THE BIDEN YEARS ADDED TRILLIONS MORE

The debt problem continued under President Joe Biden.

The federal government continued running large deficits as pandemic spending wound down and spending on existing federal programs, new legislation and interest on the debt continued.

By the time Trump returned to office in January 2025, the national debt was already far beyond the level he had once promised to eliminate.

The problem has continued during Trump's second administration.

And increasingly, simply paying interest on the accumulated debt is becoming one of the government's largest expenses.

THE $1 TRILLION INTEREST BILL

This may be the most troubling part of the entire story.

The federal government now spends more than $1 trillion annually on interest.

That money doesn't build highways.

It doesn't pay teachers.

It doesn't equip the military.

It doesn't provide health care.

It doesn't reduce taxes.

It pays the cost of borrowing money the government has already spent.

And as the debt grows, those interest expenses can grow with it.

Higher interest rates make the problem even more expensive because old government debt eventually has to be refinanced at newer rates.

The result is a cycle that becomes increasingly difficult to escape: deficits create debt, debt creates interest expenses, and those interest expenses contribute to future deficits.

$19 TRILLION TO $40 TRILLION

Trump's 2016 promise is worth remembering because it illustrates the enormous difference between campaign rhetoric and the mathematics of governing.

Eliminating $19 trillion in debt over eight years would have required an unprecedented fiscal transformation.

Instead, America went in the opposite direction.

The debt passed $20 trillion.

Then $25 trillion.

Then $30 trillion.

Then $35 trillion.

And now $40 trillion.

The country accumulated the second $20 trillion far faster than it accumulated the first.

NO EASY SOLUTION

There is no single president responsible for America's national debt, and there is no painless solution to it.

Balancing the federal budget would require some combination of spending reductions, higher revenue, stronger economic growth or changes to major federal programs.

Those choices become politically difficult very quickly.

But that reality is precisely why promises to simply wipe out trillions of dollars in debt deserve scrutiny.

In 2016, Donald Trump was presented with a $19 trillion national debt and said he believed he could eliminate it in eight years.

A decade later, the Treasury ledger tells a very different story.

More than $40 trillion.

And still climbing.b
