Michelle Obama on Wednesday weighed in on the one-year anniversary of the health care law her husband signed into law, arguing that the changes will help parents raise a generation of “happy and healthy kids.” Sharing a “personal” story in an op-ed on Yahoo’s Shine website, Obama said that as a working mom in her pre-White House days, she had “the best intentions” to feed her daughters Malia and Sasha healthy food on a budget, but admitted that “sometimes pizza or the drive-thru were inevitable.”
