In this graphic, the President's budget assumes a deficit of $603 billion in the current fiscal year - the CBO estimate is $693 billion.
The Trump budget predicts a gradual decline in the yearly deficit, finally achieving a $16 billion surplus in 2027 - but the CBO sees a deficit that year of $720 billion - a giant difference.
The President's budget estimates that the deficit will grow by $3.1 trillion over ten years - the CBO pegged that total at over $6.8 trillion.
While the White House has disputed CBO estimates involving coverage numbers under the Obama health law, and Republican health care plans, officials have said nicer things about CBO work on budget numbers.
"The CBO is a budget office," White House Deputy Press Secretary Sarah Huckabee Sanders told reporters in late June.
"And while it does very well at times predicting things on budget -- whether it’s revenue or spending -- I don’t think it does a great job -- and I think the administration has been clear and consistent that we don’t always agree that it does a great job predicting coverage."
