Reporter calls out Jen Psaki with facts after Biden admin takes credit for vaccine deal

White House press secretary Jen Psaki was confronted by a New York Times reporter on Tuesday over the Biden administration crediting themselves for brokering a deal that will allow all American adults to have access to the coronavirus vaccine within a matter of months.

What is the background?

President Joe Biden announced Tuesday that every American adult would have access to the COVID-19 vaccine by the end of May.
The remarkable feat was made possible by a new deal between pharmaceutical giant Merck & Co. and Johnson & Johnson, manufacture of the new one-shot regimen awarded emergency authorization by the Food and Drug Administration last Saturday.

During his press conference, Biden credited his administration for brokering the deal and chided his predecessor.
