Birx has been a government employee since 1980 when she joined the Army shortly after receiving her medical degree, and is now one of the country’s top immunologists.

A major caveat that could prevent Biden’s from reaching out to Birx thus far involves the new administration having to get permission from the current administration if it wishes to employ or officially approach anyone in the executive branch or any federal post.

Biden cannot technically move to form a government using current federal employees until his January inauguration, unless permission from President Donald Trump is granted to do so. Trump has not conceded to Biden or publicly accepted his loss. The President instead continues to baselessly contest the results of the election.
