Former National Security Adviser H.R. McMaster has publicly declared that he would not serve in a second Trump administration, describing his previous tenure as a 'tour of duty' and expressing his exhaustion with Trump. In a CNN interview, McMaster characterized Trump as 'extremely disruptive' and often 'very offensive,' detailing the challenges he faced while working in a chaotic environment during his time in the White House. His new book, "At War with Ourselves," critiques Trump's leadership style, citing instances of internal conflict and manipulation by foreign leaders like Vladimir Putin. McMaster acknowledged Trump's strategic insights but condemned his erratic decision-making and relationships with key officials. While he would work in any administration where he felt he could make a difference, he also indicated hesitance about serving under a potential Kamala Harris administration. Trump's spokesperson has already dismissed McMaster's book as 'fake news.'
