San Antonio Councilwoman Elisa Chan

San Antonio Councilwoman Elisa Chan resigned Monday in order to run for higher office.

Chan made national headlines over the summer when a recording of a staff meeting was leaked ad she was heard calling gays “disgusting” when discussing the city’s proposed nondiscrimination ordinance. The ordinance later passed without her support.

In her resignation letter, Chan said she was proud of her work on the council.

“I have done my best to represent the conservative values of these fine people,” she wrote. “The people of this district take an active role in deciding policy, giving their input, volunteering their time and listening to the views of their neighbors.”

Chan said last month she plans to challenge Republican incumbent Donna Campbell to represent Senate District 25.

Campbell authored a bill earlier this year to prevent transgender people from using an affidavit of a sex change to obtain a marriage license.

Chan’s last day in office is Oct. 18.
