The Trump administration has been deflecting blame and offering shifting explanations for a leak in which Defense Secretary Pete Hegseth used the unclassified app Signal to share sensitive details about an imminent attack. President Trump has called the journalist a 'total sleazebag' and blamed former President Joseph R. Biden Jr. for not having carried out the strike on Yemen. National security experts have questioned whether the information shared was classified, given its specificity and potential consequences. The White House has insisted that the information shared was an 'attack plan' and not a 'war plan,' but experts argue this is a distinction without a difference.
