A protest group called Clown Bloq says they will meet at Jackson and LaSalle for what they are calling a "last minute training action" and "dress up."
The group will then be heading to Grant Park for the biggest anti-NATO rally of the weekend, where thousands are expected to protest the NATO summit, which begins on Saturday afternoon.
Things got heated as protesters and police clashed near the downtown intersection of State St. and Washington Saturday evening. Six arrests were made.
