The Federation for American Immigration Reform has released a new report estimating the illegal alien population is now 13.2 million.
That's up 6 million from the 2000 estimate of the now-defunct Immigration and Naturalization Service.
FAIR President Dan Stein said President Bush deserves the blame.
"Almost from the day the Bush administration took office, they made it clear that their aim was to reward illegal immigration with amnesty and assorted other benefits. As a result, we have seen record increases in illegal immigration, mounting burdens on taxpayers, and unprecedented public concern about this issue," he said.
