NATO protesters arrested outside Obama's campaign headquarters

CHICAGO — A rally outside President Barack Obama's campaign headquarters in downtown Chicago ended with several arrests after some protesters refused to leave the building.

The protest was organized by a group called Catholic Workers and began Monday with demonstrators gathered outside the Prudential Building, where they sang folks songs.

Some of the protesters later entered the building's lobby where they read a statement. Police arrested about a half-dozen activists who refused to leave after the statement was read.

The Catholic Worker group is launching what organizers call a “Week Without Capitalism” in protest of the upcoming NATO Summit in Chicago. They're calling for more money to be spent on helping the poor and less on war.
