Obama said her words were taken out of context in the video and her husband's presidential campaign said the attack was "shameful," CNN reported.

"While Mrs. Obama has trouble being proud of the country where she earned degrees from Princeton University and Harvard Law School and then became a multimillionaire, her husband makes statements that belittle average Americans' response to the difficulties of life," a statement paired with the video on the Republican party's Web site reads.

Obama has defended her February statement that sparked the attack and said she was specifically referring to how proud she was of Americans "engaging in the political process."

"This is a shameful attempt to attack a woman who has repeatedly said she wouldn't be here without the opportunities and blessings of this nation," Obama spokesman Hari Sevugan said.
