MINNEAPOLIS — A new national Web campaign that encourages young people to post striptease videos of themselves as a way of raising clothing donations for homeless youths has quickly run into a firestorm of protest from some of the groups it is supposed to benefit.

A national network that serves homeless youths said Saturday it is reconsidering the controversial campaign after Catholic Charities and other outraged groups in Minnesota and across the country complained that the effort is inappropriate and exploits young people.
