This television frame grab shows CNN broadcasting the Supreme Court's decision incorrectly on President Barack Obama's health care law on Thursday, June 28, 2012. Both CNN and Fox News Channel incorrectly reported Thursday that the law's central provision, requiring virtually all Americans to have health insurance, had been struck down.
