Some charity officials in Southern California have started to run into fund-raising problems since Hurricane Katrina hit the Gulf Coast, and many others fear a drop in donations to non-relief causes, the href="http://www.latimes.com/news/local/la-me-lagives10sep10,1,4067878.story">Los Angeles Times reports. The Red Cross in Riverside County, for example, has had to lay off several employees because all gifts are earmarked for Katrina relief. Other groups have had to delay or cancel fund-raising events. Several charity officials say donations were already down because of ties to the South Asian Tsunamis.
