"The Homeland Security Committee of the House of Representatives issued a report ....entitled, "A Line in the Sand: Confronting the Threat at the Southwest Border":
http://hsc.house.gov/PDFs/InvestigaionsSubcommitteereport.pdf
"This report was prepared by the Subcommittee on Investigations of the House Committee on Homeland Security that is chaired by Representative Michael T. McCaul (R-Austin). According to the report, it is estimated that anywhere from 4 million to 10 million illegal aliens entered the United States illegally in 2005."

Note that the HSC report is now, not suprisingly, erased from cyberspace.
Between 4 and 10 million illegals crossed over in one year (2005), and the gov't now wants us to believe there are 20 million here in total? More like 50 million. .....the vast majority of whom will, after the upcoming amnesty, undoubtedly be voting Donkey.
FYI, I came across that report a couple days ago

PREPARED BY THE MAJORITY STAFF OF THE HOUSE

Whatever the number, it is an invasion. And the large number of illegal aliens calls for extensive deportations - this can be accomplished readily by both direct and indirect means. President Eisenhower did it, and we can do it now.
