Congressional Democrats, led by Representative David Cicilline of Rhode Island and Senator Jeff Merkley of Oregon, on Thursday introduced a bill that seeks to ban anti-LGBT discrimination in all areas of civil rights law.

If approved, the bill, titled the Equality Act, would prohibit anti-LGBT discrimination in seven key areas, including credit, education, employment, federal funding, housing, jury service and public accommodations, by effectively expanding the Civil Rights Act, originally approved in 1964.

While many states have banned discrimination based on sexual orientation and gender identity in employment, this patchwork of state laws leaves the majority of LGBT Americans unprotected.

Three major corporations endorsed the proposal right out of the gate, including Apple, the Dow Chemical Company and Levi Strauss & Co.

“[T]he time has come in this country for full, federal equality for the LGBT community,” Levis Strauss & Co. said in a written statement. “Ensuring fairness in our workplace and communities is both the right thing to do and simply good business.”

“At Apple we believe in equal treatment for everyone, regardless of where they come from, what they look like, how they worship or who they love,” Apple said. “We fully support the expansion of legal protections as a matter of basic human dignity.”

The bill, however, is not expected to gain much traction in the Republican-led House.
