Read the statement in full:

"Yesterday, I was removed from my positions as the Director of the Biomedical Advanced Research and Development Authority (BARDA) and HHS Deputy Assistant Secretary for Preparedness and Response by the Administration and involuntarily transferred to a more limited and less impactful position at the National Institutes of Health.

My professional background has prepared me for a moment like this -- to confront and defeat a deadly virus that threatens Americans and people around the globe. To this point, I have led the government's efforts to invest in the best science available to combat the COVID-19 pandemic.

I also resisted efforts to fund potentially dangerous drugs promoted by those with political connections.
