On February 18, 2008, Michelle Obama commented that "People in this country are ready for change, and hungry for a different kind of politics and let me tell you something, for the first time in my adult life, I am really proud of my country because it feels like hope is finally making a comeback." As the campaign soon clarified, "anyone who heard her remarks... would understand that she was commenting on our politics," not on America itself.  Still, her comments caused controversy, with many critics questioning why she wasn't proud of America before. 
Michelle's comments were edited to remove the word "really":
As of yet it is unclear who edited her statement, but clips of her statement have been edited to remove the word "really" from her comments. Here is the edited clip. It is unknown who did the editing, but it appears to have been malicious:
Michelle clarifies her remark:
“What I was clearly talking about was that I’m proud in how Americans are engaging in the political process,” she said.
“For the first time in my lifetime, I’m seeing people rolling up their sleeves in a way that I haven’t seen and really trying to figure this out — and that’s the source of pride that I was talking about,” she added.
When asked if she had always been proud of her country, she replied “absolutely” and said she and her husband would not be where they are now if not for the opportunities of America."
