Do you have a cite for your accusation or are you just expressing an opinion?
Of particular note is the following . . .
Barely two months after the September 11 attacks, New York City Mayor Michael Bloomberg stated his commitment to preserve the Big Apple as a formal sanctuary for illegal aliens. "People who are undocumented do not have to worry about city government going to the federal government," Bloomberg vowed. This assurance was stunning coming from the new mayor of a city still covered in rubble as a result of foreign terrorists who exploited our lax immigration policies at every turn.
But Bloomberg was simply following in the bipartisan footsteps of his predecessors. New York City's sanctuary policy was created in 1989 by Mayor Ed Koch and upheld by every mayor succeeding him. When Congress enacted immigration reform laws that forbade local governments from barring employees from cooperating with the INS, Mayor Rudy Giuliani filed suit against the feds in 1997. He was rebuffed by two lower courts, which ruled that the sanctuary order amounted to special treatment for illegal aliens and were nothing more than an unlawful effort to flaunt federal enforcement efforts against illegal aliens. In January 2000, the Supreme Court rejected his appeal, but Giuliani vowed to ignore the law.
Stick a fork in him -- he's done. This is precisely the kind of information that is going to get a lot of scrutiny during the GOP primaries and/or the general campaign in 2008 -- and it's just one thing among many that's going to lead him to a defeat of embarassing proportions.
