After months of promising his Build Back Better spending agenda would be “fully paid for” and would even “cost zero dollars,” President Joe Biden is being hoisted by his own petard. The Congressional Budget Office is set to burst that bubble Friday with a budget score showing that the Biden agenda will add hundreds of billions to the national debt.

The biggest difference between the White House and CBO estimates is the former’s unreasonable claim that the IRS can raise an additional $400 billion if it is given $80 billion for additional enforcement. The CBO estimates that the IRS can find only $120 billion in extra revenue with that money.
