The memorandum Obama signed Wednesday is not expected to grant health and retirement benefits to same-sex partners, as that is prohibited under the Defense of Marriage Act.

"It will absolutely be seen as something good -- but I think, for example, it not including full health insurance -- that is going to put a real microscope on that question. You know, why not?" Kim said, adding that the memo applies only to federal employees, so most people will not be affected by it.
