When making donations, federal officials are urging caution. The FBI warns that con artists often prey on donors responding to charity calls in the wake of natural disasters. The Internet Crime Complaint Center in Boise, Idaho, says donors should be careful when confronted with unsolicited e-mails asking for credit card information or money transfers.
