Tornado Relief

How Much Of The $$ Goes To Help Tornado Victims?I see the latest "text $10 offer" to the Red Cross. In this case, it's a very worthwhile relief fund for the Springfield area. My inquiry: What percent of this $10 goes directly to relief efforts to those affected? And how much goes to Red Cross administrative costs? I hear Red Cross isn't an "efficient" charity. Can you clarify? - Richard, Watertown
