Senator Tom Harkin of Iowa has been pressuring President Obama to sign the Employment Non-Discrimination Act (ENDA). (http://www.aclu.org/hiv-aids_lgbt-rights/employment-non-discrimination-act)
The ENDA is an intended Federal legislation that would ban discrimination on the basis of sexual preference on the Federal level. Such protections already exist in some states, including New York State, however the Federal government has notably lagged behind on providing similar protections.
Unfortunately, it appears that the ENDA is unlikely to be passed by the current House and so Senator Harkin is pressuring the President to sign the ENDA as an executive order. This would really only extent protection to employees working for the Federal Government and Federal contractors, but it would be a step in the right direction.
Senator Harkin stated, "marriage equality is really the civil rights issue of our time and that time has come. I think more and more people are saying, 'Yes, time to put that behind us.' We did that in Iowa. Yeah, there's always some who want to turn the clock back. Heck, I bet you can find people today who would like to to turn back the Civil Rights Act of the 1965. They want to get rid of the Voting Rights Act. There's always people like that. but I think the great bulk of Americans would just as soon say, 'That's history, we're beyond that."
