Haberman had a duty to her employer, and to the American public, to reveal this information in real time, not to wait until her book came out two years later. Her reporting proved what many were saying about Trump prior to the election, and had she released this information properly more could've been done to oppose Trump's lies about the election results and to prevent the Jan. 6 Capitol riot.
Liberals are in a tizzy because Haberman revealed one of their favorite things – dirt on Trump – but not in a timely enough manner. Haberman has always been a shady reporter, but liberals didn't seem to mind when she and her colleagues at The Times reported on alleged connections between Russian election interference and the Trump campaign, despite a lack of conclusive evidence. She clearly has an anti-Trump agenda and this is a non-story.
