Levine was appointed as Pennsylvania's physician general in 2015 and confirmed as acting secretary in 2018. Biden’s transition team noted that Levine — appointed by Democratic Governor Tom Wolf in 2017 — was confirmed three times by the Republican-controlled state Senate to serve as secretary of health and the state’s physician general. She's been the public face of Pennsylvania's response to COVID-19, garnering criticism from some for implementing stricter lockdown policies, as well as allegedly "mishandling" the spread of COVID-19 in nursing homes, the Philadelphia Inquirer reports. Levine's critics, including certain fellow officials, have often resorted to baseless, transphobic attacks.

In a press release responding to the announcement, the National Center for Transgender Equality said the nomination was "groundbreaking." If confirmed, Levine would be the highest-ranking transgender official in the country.

“President-elect Biden said throughout his campaign that his administration would represent America. Today, he made clear that transgender people are an important part of our country,” said Mara Keisling, the executive director of the National Center for Transgender Equality.

Other transgender advocacy groups took to Twitter to congratulate Levine's nomination.

In a press release issued Tuesday afternoon, prominent LGBTQ civil rights group Lambda Legal also praised the nomination, noting the significance of having a member of the LGBTQ community guiding the new administration's health policy.

"Dr. Levine’s life experience also gives her a unique understanding of not only the needs of the LGBTQ community but also the importance of paying attention to those who have been historically excluded and marginalized by our medical system," wrote Lambda Legal CEO Kevin Jennings, "thus enabling her to play an especially important role in helping HHS fulfill its mission ‘to enhance the health and well-being’ of allAmericans."

Biden's nomination for assistant secretary of health follows previous announcements that LGBTQ protections would be included in his first actions as president — a marked departure from the current administration's previous policies.

President-elect Biden will be sworn into office Wednesday, Jan. 20.
