PROVIDENCE, R.I. - Ann Romney's debut on Twitter couldn't have come at a more opportune time.
Ann's first tweet came just moments after Democratic strategist and DNC adviser Hilary Rosen lobbed an insult at Ann Romney, suggesting that the 64-year-old mother of five and grandmother of 16 had never held a job.
"Guess what, his wife has actually never worked a day in her life," said Rosen, who was being interviewed by CNN's Anderson Cooper about the "war on women."
And then, just like that, a familiar name popped up on Twitter: @AnnDRomney.
"I made a choice to stay home and raise five boys. Believe me, it was hard work," Ann tweeted.
The Romney campaign confirmed to ABC News that the account belongs to Ann Romney.
The tweet came just as husband Mitt wrapped up a second day of campaigning that all but entirely focused on the "war against women," packing events with female business leaders and accusing the Obama administration's economic policies of hurting women.
"I could not disagree with Hilary Rosen any more strongly. Her comments were wrong and family should be off limits. She should apologize," Obama campaign manager Jim Messina said in a tweet.
Top Obama campaign strategist David Axelrod also tweeted his disapproval: "Also Disappointed in Hilary Rosen's comments about Ann Romney. They were inappropriate and offensive."
Following the interview, Rosen herself tweeted, "I've nothing against @AnnRomney. I just don't want Mitt using her as an expert on women struggling $ to support their family. She isn't."
"@AnnDRomney Please know, I admire you. But your husband shouldn't say you are his expert on women and the economy," said Rosen.
Then Rosen offered a welcome message to Ann, tweeting, "oh and @AnnDRomney welcome to Twitter. You will find it a very exhilarating and often unforgiving place!"
