Boy Scouts of America says it is disappointed Caterpillar Inc. will no longer give money to the group. But public relations director Deron Smith on Thursday thanked the Peoria-based heavy equipment manufacturer for its past support. Caterpillar spokeswoman Rachel Potts said Thursday that the Caterpillar Foundation has decided to withdraw its supports for Boy Scouts of America. Potts says the company believes the group's policy barring homosexual adults from serving as scout leaders is discriminatory.
