We know Donald Trump demands the media give him and his supporters special treatment, but they still should feel an obligation to correct their outright lies.

Stephen Miran, the chairman of the president’s Council of Economic Advisers, was cited in a New York Times article as saying that “congressional analysts and others had underestimated the effects of Mr. Trump’s initial tax cuts, and had done the same this year.”

It is easy to show that this is not true. In its projections from April of 2018, after the passage of Trump’s tax package, the Congressional Budget Office (CBO) projected the economy would grow by 3.0 percent in 2018 and 2.9 percent in 2019. The economy actually grew by 3.0 percent in 2018 and just 2.6 percent in 2019.

This means that CBO overestimated the extent to which Trump’s tax cuts would spur growth. The New York Times should have corrected Miron’s error so that readers wouldn’t be misinformed.
