  the employment non-discrimination act (enda) is legislation proposed in the united states congress that would prohibit discrimination in hiring and employment on the basis of sexual orientation or gender identity by employers with at least 15 employees. enda has been introduced in every congress since 1994 except the 109th. similar legislation has been introduced without passage since 1974. the bill gained its best chance at passing after the democratic party gained the majority after twelve years of republican majorities in the 2006 midterm elections. in 2007, gender identity protections were added to the legislation for the first time. some sponsors believed that even with a democratic majority, enda did not have enough votes to pass the house of representatives with transgender inclusion and dropped it from the bill, which passed the house and then died in the senate. president george w. bush threatened to veto the measure. lgbt advocacy organizations and the lgbt community were divided over support of the modified bill. in 2009, following democratic gains in the 2008 elections, and after the divisiveness of the 2007 debate, rep. barney frank introduced a transgender-inclusive version of enda. he introduced it again in 2011, and sen. jeff merkley introduced it in the senate. on november 7, 2013, merkley's bill passed the senate with bipartisan support by a vote of 64-32. president barack obama supports the bill's passage. ==evidence of employment discrimination on the basis of sexual orientation and gender identity==  in states that have anti-discrimination policies in place, lgb complaints are equivalent to the number of complaints filed based on sex and fewer than the number of complaints filed based on race.evidence discrimination based on sexual orientation occurs at a similar rate as sex and race at 4.7 per 10,000, as compared to discrimination based on sex at 5.4 and race at 6.5.{{cite web|last=ramos|first=christopher|title=evidence of employment discrimination on the basis of sexual orientation and gender identity: complaints filed with state enforcement agencies, 1999â2007|url=http://
