Former Congressman Tom Tancredo, known for his fierce stance against illegal immigration, has been blocked from speaking at Providence College in Rhode Island, according to The Associated Press, which writes that the Roman Catholic college cited a technicality: The student group that invited Tancredo is not officially recognized by the college. The statement also notes that Tancredo's position on illegal immigration "directly contrasts" the view of Thomas Tobin, a bishop of Providence who has spoken against immigration raids and who sits on the college's Board of Trustees. Tancredo, a Colorado Republican who declined to run for another term in Congress and instead launched a presidential campaign last year, could return to the college later, reports The Providence Journal, which quotes school officials as saying they would prefer a discussion on immigration that would encourage multiple points of view. The Journal adds that Tancredo instead will speak to Rhode Islanders for Immigration Law Enforcement tonight.
