If you are talking about the new tax bill, then you have your facts wrong. The CBO has stated that the tax bill will add 1.5 trillion dollars to the debt over the next ten years, however they are basing that on the GDP averaging 1.9%, as it was for the last 8 years. This year, the first year of Donald Trump’s Presidency, the GDP has averaged over 3%. The CBO has also stated that if the GDP averages over 2.5% there will actually be a surplus at the end of the ten year period, NOT a deficit.
