A Los Angeles judge has granted a preliminary injunction against a political action committee associated with political activist and economist Lyndon H. LaRouche Jr. that has been soliciting donations in front of grocery stores in Southern California.

LaRouche has compared President Obama’s proposed health care reforms to those of Adolf Hitler. In July, The Kroger Co., which owns the Ralphs and Food 4 Less chains, filed suit against the LaRouche Political Action Committee, which is based in Leesburg, Va.
