tancredoDuring an appearance on the radio show of Fox News’ Alan Colmes, prominent tea party leader Tom Tancredo made it clear he believes President Obama may not be an American citizen, Think Progress reported.

The former GOP congressman responded to questions about a statement he gave to a group of tea partiers: “If his wife says Kenya is his homeland, why don’t we just send him back?�

Tancredo was referring to a speech by Michelle Obama in which she calls Kenya the president's "home country."

The following is a partial transcript from the interview:

COLMES: Do you really believe – you know he was born in Hawaii right?

TANCREDO: I have absolutely no idea where he was born.

COLMES: You’ve seen he was born in Hawaii; he was in two Hawaiian newspapers within two days of his birth.

TANCREDO: Anybody can put an article in a newspaper. Just show me your birth certificate!

Later in the interview, Tancredo suggested the Obama administration will not release the president's birth certificate as a ploy to cast tea partiers in a negative light.

TANCREDO: Now they very well not want to show it because they want to propagate this whole thing that’s going on about birthers. … They may be doing it for that reason; I don’t know why they don’t want anyone to see it. … They want it propagated because you know –

COLMES: It makes your party look nuts!

TANCREDO: Yeah well maybe that’s why they don’t produce document, I don’t know.

It doesn't look like the "birther" movement will dissipate any time soon. Americans who deny that the president is a natural-born citizen are preparing to march on the capital May 29 to voice their concerns.

A bill in Arizona, which would require the Arizona secretary of state to review and approve a presidential candidate's birth certificate before letting the candidate's name appear on the state ballot, still awaits approval from the state senate.

And U.S. Senate candidate J.D. Hayworth has been critical of the "birther bill" not because the president has already proved his citizenship, but because the bill doesn't go far enough. Hayworth said the bill should ensure that all politicians should be required to produce birth certificates, and not just presidential candidates.
