Tom Homan reacted on Monday on Fox & Friends to a study saying the number of illegal immigrants currently in America may be double the estimated amount.

The study, conducted by researchers from Yale University and the Massachusetts Institute of Technology, estimated that an average of 22 million undocumented immigrants are living in the United States.

Researchers took into account the number of deportations, border apprehensions and visa overstays to support their findings.

"I think this gives the president more ammunition to say 'Look, we need to fix this border,'" said Homan, former director for Immigration and Customs Enforcement.

The study's researchers said that the current 11.3 million estimate is based largely on survey data from the Census Bureau.

Homan added that even though he's not sure what set of numbers to believe, the study shows the need for total immigration reform.

"How much bigger than 12 million do you need to be to recognize there's a problem?" he said.

Homan implored Americans to make it known to their local politicians that immigration reform needs to be taken seriously.
