From this:

A former INS official who attended meetings with Rahm Emanuel when Emanuel was a White House aide says the hard-charging Democrat relaxed rules to naturalize even criminal immigrants and secure their votes for President Clinton ahead of the 1996 presidential election.

...Emanuel coordinated with Hispanic community organizers in Chicago to rubberstamp immigrants for citizenship, the INS official said in an exclusive interview with WND...

The program in question was Citizenship USA, run out of Al Gore's office and involving former INS Commissioner Doris Meissner. One of the organizations involved was the Chicago-based United Neighborhood Organization, run by Danny Solis, brother of the former Hillary Clinton campaign manager Patty Solis Doyle.

Apparently the various claims of the INS official are buttressed by the 2000 Department of Justice report "An Investigation of the Immigration and Naturalization Service's Citizenship USA Initiative" available here. Since there are a lot of PDFs, if anyone can look through those for Emanuel-related information that would be appreciated.

Continuing:

"He got every rule changed in the hiring of adjudicators so they could naturalize more Mexican nationals to vote for Bill Clinton, not to mention getting the rules changed to naturalize anyone," regardless of their criminal background, said the official, who's still employed by the federal government and requested anonymity to avoid reprisals.

"They had immigration ceremonies at stadiums with DNC (Democratic National Committee) staff registering them as voters right there," he added.

...Another former INS official, William Carroll, said Emanuel "took midnight trips to INS headquarters to meet with (Commissioner) Doris Meissner about Citizenship USA."

He said that in March 1996 he and other INS district directors were given "marching orders" by headquarters to push through as many new citizens as possible ahead of the election, even if no criminal and national security background checks were completed. INS deportation officer Tom Conklin said that he and other agents were pressured to rubberstamp immigrants "with two or three arrests for crimes like burglary..."
