Crazy eyes.

The controversial head of President Biden’s new Big Brother-like disinformation board drew fresh mockery and disdain Friday over cringeworthy TikTok footage of her adaptation of a Mary Poppins song to be about misinformation.

Nina Jankowicz’s newly resurfaced take on the “Supercalifragilisticexpialidocious” tune was being shared widely online Friday after it emerged she has her own history of spreading disinformation online.

“Information laundering is really quite ferocious. It’s when a huckster takes some lies and makes them sound precocious, by saying them in Congress or a mainstream outlet, so disinformation’s origins are slightly less atrocious,” Jankowicz sang in her Feb. 2021 TikTok video.
