Louie Gohmert "is so off the mark" in his assertion that terrorists are plotting to conceive babies in the United States so they can grow up to kill Americans.

The Republican congressman first made the claim on June 24, while discussing on the House floor what he felt were serious gaps in our border enforcement.

"They [terrorists] would have young women who became pregnant, would get them into the United States to have a baby-they wouldn't even have to pay anything for the baby-and then they would return back where they could be raised and coddled as future terrorists," Gohmert said. "And then one day, 20, 30 years down the road, they could be sent in to help destroy our way of life."

Napolitano, in a Friday interview on CNN's The Situation Room with Wolf Blitzer, said that she has seen no evidence of such a plot.
