The City of Chicago has revoked the permit for a Daley Plaza demonstration by National Nurses United, citing the group's plan to feature a performance by guitarist Tom Morello.
The demonstration, preceded by a march, was scheduled for the weekend of the NATO summit and had been approved by the city months ago, the Trib says.
In a letter to the union, a city official noted that the performance by Morello, Morello, formerly of Rage Against the machine, would lead to a larger crowd, and said the event needed to be moved to the Petrillo Music Shell.
RoseAnn DeMoro, the union's director, says the group is considering a legal challenge.
