Birx confessed to manipulating data and quietly altering CDC guidance without the administration's knowledge or authorization.

In "Silent Invasion," she discusses how 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.

WND reported:

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.

She and then CDC Director Robert Redfield "agreed to quietly rewrite the guidance and post it to the CDC website."

"We would not seek approval. Because we were both quite busy, it might take a week or two, but we were committed to subverting the dangerous message that limiting testing was the right thing to do," she writes.
