The nation’s $16.6 trillion debt limit is set to expire on March 15.

The White House has said that it is willing to negotiate a short-term extension if the country can find a way to lower its $16 trillion debt burden.

The debt ceiling is a key issue in the budget negotiations between House Speaker John Boehner and President Obama.

The U.S. owes $15.7 trillion in federal debt, more than half of which is owed to the federal government.

The country has a $2.2 trillion credit rating on the S&P 500.

But the U.N. has said the U,S.

and European Union countries are in default and the debt ceiling has to be raised.

What to know about the U in default, what it means, and what it could mean for the economy.

Here are some key points about the debt crisis:What is the U?

The U is the largest single source of federal debt.

It is the only country that has defaulted on its debts, and it has become the defaulting country.

That means that the U has the largest debt burden on the world.

According to the International Monetary Fund, the U is in default of more than $1.6tn.

How do we pay down the debt?

The debt is backed by a variety of government spending and revenues.

The government typically takes in money from the public through various means.

It typically borrows from other governments, but the Treasury Department also has the ability to use the money to pay interest on its debt.

The interest paid on its borrowed money is used to pay down its debt, as well as pay interest payments on its outstanding debt.

How does it affect the economy?

In a world of austerity, the debt is seen as a key source of income for many countries.

But in some countries, such as Greece, the burden of the debt has fallen dramatically and has led to a recession.

This is happening in part because some countries have been borrowing to pay for debt relief programs.

For example, in the U and Europe, the European Union has extended some of its debt relief program to countries like Greece.

How could the U be in default?

According to The International Monetary Board, the nation has defaulting on its loans.

The reason the U can’t pay back its debts is because it owes so much money to the U that it can’t make its payments on time.

In addition, the country’s debt is tied to a number of foreign governments.

If one of these foreign governments defaults, the value of the U’s assets in the international market drops significantly, which can lead to economic problems.
