It's the one that aims to decimate the low-income housing programs.
Here's a letter from the American Association of People with Disabilities in opposition. Notice all the groups that have signed it.

The program changes proposed by the bill would be devastating to those currently participating in HUD affordable housing programs as well as to the millions in need of such assistance. For example, latest data show that, nationally, 84% of severely cost burdened households in the United States are extremely low income households. This legislation would set the stage for a shift of housing assistance away from families most in need of affordable housing and increase the number of homeless people in our country.

I don't know if this is up for a vote anytime soon, or if it is stalled in the wake of Katrina, or what. Any info would be appreciated. And while you're at it, please write your representatives in opposition to this horrible bill.
