先前，一些共和党人称奥巴马可能并非生于美国，因而质疑他的执政合法性。美国总统贝拉克·奥巴马竞选网站18日开始发售印有他出生证明的t恤。
washington – you've seen president barack obama's birth certificate. now you can wear it.
想必你已经看过奥巴马的出生证明了吧，现在，你有机会穿上印有印有他出生证明的t恤。
the obama campaign is selling t-shirts on its website that show obama's face on the front along with the words "made in the usa."
奥巴马竞选网站上开始出售印有奥巴马出生证明的t恤。t恤正面印有奥巴马头像，头像下面还写着“美国制造”的字样。
on the back is an image of the president's long-form birth certificate from hawaii — the one the white house finally produced in april in an attempt to squelch the "birthers" who claim obama is not a natural-born u.s. citizen, and therefore ineligible to be president.
而t恤的背面是奥巴马详版夏威夷出生证明。曾有人就奥巴马出生质疑执政资格。今年四月，白宫也公布一份夏威夷州签发的详细出生证明，回应外界质疑。
starting price for the t-shirts — described on the website as "limited edition" — is $25.
奥巴马竞选网站称，该限量版t恤的起价是25美元。
