It seems to me that this Associated Press story speaks for itself:
WASHINGTON (AP) — The U.S. government has mistakenly granted citizenship to at least 858 immigrants from countries of concern to national security or with high rates of immigration fraud who had pending deportation orders, according to an internal Homeland Security audit released Monday.
The Homeland Security Department’s inspector general found that the immigrants used different names or birthdates to apply for citizenship with U.S. Citizenship and Immigration Services and such discrepancies weren’t caught because their fingerprints were missing from government databases.
The report does not identify any of the immigrants by name, but Inspector General John Roth’s auditors said they were all from “special interest countries” — those that present a national security concern for the United States — or neighboring countries with high rates of immigration fraud. The report did not identify those countries.
