Aditi Hardikar, the Obama administration’s primary liaison to the gay, bisexual and transgender community for more than a year, is stepping down Tuesday, the White House said.

Hardikar will join former Secretary of State Hillary Clinton’s presidential campaign as finance director for coalitions, according to Hardikar.

White House officials credited her with playing a critical role in some of the administration’s more cutting edge and controversial moves on gay and transgender rights, such as the opening of the first-ever all-gender restrooms at the White House and the decision to light up the White House in rainbow colors the day the Supreme Court legalized same-sex marriage nationally.

“Aditi’s fingerprints are all over many of this administration’s most important steps forward,” Valerie Jarrett, senior adviser to President Obama, said in a statement, adding that Hardikar’s work “showed that change is possible when you are dedicated to something larger than yourself.”

The White House did not announce a successor to Hardikar, who also served as a liaison to Asian American and Pacific Islander communities.
