Yep, I thought the percentage was much lower AND I thought Chelsea drew a salary.
The true amount they gave to charitable work was 6%. The rest was spent on travel, rent, salaries, bonuses, fundraising, and other overhead. I read that they spent on office supplies was more than they spent on the needy.
