Margarita Alvarez, union spokesperson with the organization, Voices United for Immigrants, addresses the public during the protest carried out on Saturday in front of City Hall in Dallas. Thousands participated in the protest on Saturday outside the City Hall and also there were dozens of banners and posters which asked for "Justice for the undocumenteds," "Equality of rights," or "No to the wall." But it was a single feeling which united the more than 2,000 persons protesting H.R. 4437 presented to Congress by Congressman James Sensenbrenner (R-WI).
