Some conservatives are upset over t-shirts bearing the logo "Together We Thrive: Tucson & America" that were handed out to attendees at tonight's memorial service in the McKale Center on the campus of the University Of Arizona here.

The shirts, which bear the same logo that adorns other items from the event -- including press passes, signage and volunteer t-shirts -- were placed on many of the seats in the lower sections of the arena when tonight's capacity crowd walked in.

The University Of Arizona did not immediately respond to requests for more information on the shirts, which are drawing fire in the conservative twitter- and blogosphere tonight.
