Check post #91 (brackets added by me).
He [Giuliani] was active in promoting the [Reagan] Administration's immigration bill last year, which sought to grant amnesty to Illegal aliens already in the country and to impose sanctions on employers for hiring illegal aliens in the future.
So he's still arguing for amnesty like before...but when it came down to sanctions on employers, he reneged on this by suing the federal government when they passed legislation to increase communication between employers and the INS. From the original Frontpage article up-top:
Rudolph Giuliani sued all the way up to the Supreme Court to defend the citys sanctuary policy against a 1996 federal law decreeing that cities could not prohibit their employees from cooperating with the INS.
Ironic, ain't it? [Actually, I think it's pretty pathetic!]
