evidence: Sen. Graham’s false claim about Build Back Better adding $3 trillion in deficits [...] Graham’s press office sent us a Dec. 10 letter from the CBO. The agency did say the deficit would go up by $3 trillion, but that was for, as they put it, "a modified version of H.R. 5376, the Build Back Better Act." [...] Graham said the CBO predicted the Build Back Better Act would add $3 trillion to deficits over 10 years.
