WASHINGTON (AP) — President-elect Joe Biden has tapped Pennsylvania Health Secretary Rachel Levine to be his assistant secretary of health, leaving her poised to become the first openly transgender federal official to be confirmed by the Senate. Levine is a pediatrician and former Pennsylvania physician general and was appointed to her current post by Democratic Gov. Tom Wolf in 2017. Levine is one of the few transgender people serving in elected or appointed positions nationwide. Levine won past confirmation by the Republican-majority Pennsylvania Senate and has emerged as the public face of the state’s response to the coronavirus pandemic.
