ANSWER has also been involved in the much larger demonstrations in opposition to the Sensenbrenner Bill and support of legalization for undocumented immigrants that have occurred across the United States since March 2006. ANSWER was not the primary organizer of the initial large protests in Chicago, Los Angeles, and Dallas in late March and early April, but endorsed them. ANSWER was more prominent in the promotion of a May Day "Day Without An Immigrant" strike and boycott, because this call was controversial within the immigrant rights movement, contributing to a growing division between its left-wing advocates and moderates who believed a strike and boycott would be counterproductive.[28]
