WASHINGTON (CNN) -- The House majority leader late Tuesday tried to deflect criticism of the federal response to Hurricane Katrina by saying "the emergency response system was set up to work from the bottom up," then announced a short time later that House hearings examining that response had been canceled.
Rep. Tom DeLay, R-Texas, said House Republican leaders instead want a joint House-Senate panel set up to conduct a "congressional review" of the issue.
