(CNN)-- Michelle Obama became the latest high-profile figure to weigh in on the stirring controversy over comments made against Ann Romney.
The first lady responded on Twitter after a top Democratic strategist and CNN political contributor criticized Ms. Romney, who stayed at home to raise her five sons, as having "never worked a day in her life."
"Every mother works hard, and every woman deserves to be respected," the first lady's Twitter account read on Thursday.
While Obama's staff typically handles her account, the tweet was signed with her initials, "-mo," meaning the first lady supposedly typed out the tweet herself.
Hilary Rosen made the original comments Wednesday night on CNN, arguing Ann Romney was out of touch with working class women because she chose not to enter the workforce and stay at home with her children, instead.
The remarks immediately set off a wave of responses from Republican and Democratic leaders alike, including staff members from the president's re-election campaign, condemning Rosen's comments.
Rosen further clarified her statements in a column Thursday, saying she meant Ann Romney was not the best example on the campaign trail as her husband's "touchstone for women who are struggling economically."
