According to the the National Transgender Advocacy's blog:
The National Transgender Advocacy Coalition (NTAC) is issuing a call to join numerous individuals and members of other organizations in protesting the lavish October 6th annual HRC National Dinner in Washington, DC. Representative Nancy Pelosi, Speaker of the House, will be featured as Keynote at the event.
We are very disappointed and angry that any civil rights organization claiming to advocate for our rights can turn their backs on us when the going gets tough. It amounts to a betrayal, since HRC earlier promised to support only an inclusive ENDA.
