The United States national debt surpassed a record $40 trillion

The U.S. national debt this week surpassed a record $40 trillion, a staggering milestone as defense costs, social programs like Social Security and Medicare and interest on the burgeoning deficit make up an enormous share of federal spending.

The milestone figure was recorded just five months after the U.S. hit a record $39 trillion debt in March. It reached $38 trillion five months before that, in October.

The unprecedented $40 trillion figure highlights competing administration priorities, from boosting defense spending that the U.S. relies on to carry out President Donald Trump’s almost-6-month-old war in Iran to lowering the cost of gas and groceries.

Kush Desai, a White House spokesman, said the Trump administration “has been focused on slashing waste, fraud, and abuse in federal spending while accelerating economic growth to get America’s debt-to-GDP ratio trending in the right direction.”

However, experts say the exploding debt and the latest record milestone are already affecting Americans’ pocketbooks by raising borrowing costs for things like mortgages and cars, lowering wages from businesses that have less money available to invest, and creating more expensive goods and services.
