A full-blown war of words between the first family and CNN broke out late Wednesday on Twitter, with the cable network mounting an unprecedented attack on President Trump in a jarring official statement defending a widely questioned story.

The statement from CNN came after the president mocked Watergate legend Carl Bernstein, who co-wrote the disputed report that Trump’s former lawyer was prepared to give damning information about the president to Special Counsel Robert Mueller.

CNN continues to stand by the story despite growing skepticism.

“Make no mistake, Mr. President, CNN does not lie. We report the news. And we report when people in power tell lies. CNN stands by our reporting and our reporters. There may be many fools in this story but @carlbernstein is not one of them,” CNN’s public relations department sent.
