A federal court in Chicago is preparing for a white-buffalo sighting. On April 28, the Chicago district office of the Equal Employment Opportunity Commission is scheduled to try its largest case since it settled a sexual harassment complaint against Mitsubishi five years ago for $34 million," The National Law Journal reports here.
