Dr. Deborah Birx, who served as the White House Coronavirus Response Coordinator under President Donald Trump, has admitted in a new book that she manipulated data and quietly altered CDC guidance without authorization.

In "Silent Invasion," she confesses she "devised" a "strategic sleight-of-hand" method of reporting she described as "subterfuge."

"This wasn't the only bit of subterfuge I had to engage in," she writes.

Birx insisted, contrary to the White House and the CDC, that the asymptomatic spread of COVID-19 was significant.

She says that "eight months into the pandemic, many at both the White House and the CDC still refused to see that silent spread played a prominent role in viral spread and that it started with social gatherings, especially among the younger adults."

Birx opposed the advice of then-coronavirus adviser Dr. Scott Atlas to limit testing on the premise that asymptomatic transmission was minimal and not driving the pandemic.
