Two-time Academy Award-winner Sally Field on Thursday spoke in support of the Houston Equal Rights Ordinance (HERO).

HERO prohibits discrimination in housing, employment and public accommodations based on several characteristics including race, religion, sexual orientation and gender identity.

Field joined other supporters at a press conference organized by Houston Unites, the campaign to approve Proposition 1, and the Human Rights Campaign (HRC), the nation's largest LGBT rights advocate.

“A vote for HERO is a vote to treat everyone fairly and equally under the law,” Field told reporters. “This goes to the core of who we are as Americans.”

Texas State Senator Sylvia R. Garcia also spoke at the event.

“Houston's Equal Rights Ordinance is about one thing and one thing only: fighting discrimination,” she said.

Houston voters head to the polls Tuesday.

On Wednesday, Field channeled a scene from her Oscar-winning Norma Rae performance. While walking the red carpet at an HRC event, Field held up a sign in support of HERO. In the 1979 film, Field's character fights for better working conditions at a textile factory by calling for workers to unionize. A famous image from the movie shows her character holding a sign that reads “UNION.”
