Feb. 11 (UPI) -- The nation's debt and federal deficit likely will become unsustainable and worsen by trillions of dollars over the next 10 years, the Congressional Budget Office reported on Wednesday.

The CBO predicted the federal budget deficit will reach $1.9 trillion by the end of 2026, which is equal to about 5.8% of the nation's gross domestic product.

This year's deficit is projected to be about the same as last year's, but the annual amount is expected to rise to $3.1 trillion within 10 years, which would equal 6.7% of the anticipated gross domestic product in 2036.

"Our budget projections continue to indicate that the fiscal trajectory is not sustainable," CBO Director Philip Swagel said in a prepared statement.
