That was then. This is Mao. Congressional Budget Office

From FOX News:

Biden touted CBO as 'gold standard' – now his White House is trying to undermine it
President Biden previously touted the nonpartisan Congressional Budget Office (CBO) as the "gold standard" – but now his White House is trying to undermine it.

While serving as vice president in the Obama administration, Biden said in an interview with Larry King that the nonpartisan legislative budget scorer is the "gold standard" when it comes to their work.

In fact, the president said that no members of either party call into question the CBO’s reports.

But now?  From Zero Hedge:

CBO Confirms Biden Spending Bill Not Fully Paid For, Would Cost $367 Billion Over A Decade
Just as the House Rules Committee cleared Biden's Build Back Better bill for debate by the full House with first votes on the bill set as early as 19:15EST (with Senator Manchin commenting earlier that he has not decided on whether to vote to proceed to the Build Back Better Bill), moments ago the CBO finally released its score of Biden's bill and, to nobody's surprise, it finds that contrary to what the Democrats asserted (and then un-asserted), that the bill would not fully pay for itself.

Instead, the CBO estimates that enacting this legislation would result in a net increase in the deficit totaling $367 billion over the 2022-2031 period, as a result of an additional $1.636 trillion in additional spending...

And continuing from the first article - Biden's reaction to the CBO news:

However, Biden’s confidence in the CBO has been scrutinized after White House spokesperson Andrew Bates said the nonpartisan body did not have the "experience" to weigh in on an aspect of the president’s Build Back Better agenda.

"The CBO does not have experience analyzing revenue amounts gained from tracking down wealthy tax cheats who are taking advantage of every honest taxpayer," Bates said at a press gaggle.

Much more at both sides.
