U.S. Senate candidate Rand Paul is stirring it up again, this time by saying he opposes citizenship for children born in the U.S. to parents who are illegal immigrants.

Paul, who a week ago won the GOP primary in Kentucky, told a Russian TV station in a clip circulating on political websites Friday that he wants to block citizenship to those children.

“We’re the only country I know that allows people to come in illegally, have a baby, and then that baby becomes a citizen,” Paul told RT, an English-language station, shortly after his win over GOP establishment candidate Trey Grayson. “And I think that should stop also.”

Legislation dubbed the Birthright Citizenship Act was introduced in the U.S. House of Representatives last year seeking to prevent citizenship to babies born to illegal immigrants even though the 14th Amendment to the Constitution guarantees citizenship to everyone born in the U.S. More than 90 lawmakers signed on as co-sponsors.
