Massachusetts Senator Edward Kennedy is backing a bill that bans job bias against gays, lesbians and bisexuals, but not transsexuals. And that's causing some uproar among gay rights activists.
The National Gay and Lesbian Task Force says it will "strongly oppose" the bill.
The National Center for Transgender Equality says it doesn't want Congress to push through a civil rights bill that the organization doesn't want.
Kennedy has long championed gay rights and says approval for the legislation could pave the way for passing protections for transsexual people next year, when he hopes a Democratic president who supports gay rights will be in the White House.
The bill was written by openly gay Congressman Barney Frank and approved by the House late last year.
President Bush is expected to issue a veto if the bill clears the Senate.
