A popular Spanish-language disc jockey began a cross-country trip Sunday to encourage Congress to overhaul the nation’s immigration laws, planning to give 1 million supporting letters to lawmakers in Washington, D.C. Eduardo “Piolin” Sotelo, from the nationally syndicated show, “Piolin por la Ma ana,” and several others traveling in his caravan left from a Mexican cultural landmark in downtown as several hundred fans and supporters cheered. Sotelo said he would stop in several cities before his planned arrival in Washington on Thursday. “We are knocking on the door” of immigration reform, said Sotelo. “Immigrants haven’t come here to hurt anybody, but just to work and earn money for their families.” Sotelo and other Spanish-language disc jockeys were instrumental in helping to mobilize hundreds of thousands of people to marches in the spring of 2006 in favor of immigration reform. Sotelo’s current campaign asks legal residents and American citizens to write letters in support of immigration reform that would create a path to citizenship for the estimated 12 million living in the country illegally.
