到底是奥巴马口误还是大法官口误？

大法官口误

应该是
"I, Barack Hussein Obama, do solemnly swear that I will FAITHFULLY execute the office of president of the United States, and will to the best of my ability, preserve, protect, and defend the constitution of the United States."

大法官说成:

"I, Barack Hussein Obama, do solemnly swear that I will execute the office of president of the United States FAITHFULLY, and will to the best of my ability, preserve, protect, and defend the constitution of the United States."

奥巴马知道大法官说错了, 所以犹豫了一下, 然后大法官又再说了一次, 还是错的, 奥巴马只好跟着他念错了.

大致是楼上说的那样。
第一次其实法官也意识到自己说错了 还停顿了下。 第二次法官重复说一遍的时候 法官自己都太紧张，乱说了下。。 所以还是说错了。他说了：the office FAITHFULLY execute the office of president of the United States faithfully 其实第一遍 奥巴马不停顿跟着说就没事了 那个faithfully 放前 放后 都一样的。
