Today my colleague Joshua Keating and I are focusing on Donald Trumps firing of high-ranking military officials, a move that cements the militarys new anti-DEI mandate now and could have even bigger consequences later.Whats the latest? Trump on Friday night fired Charles Q. Brown Jr. the chair of the joint chiefs of staff and nominated retired Air Force Lt. Gen. Dan Caine to replace him. Also fired were the chief of naval operations, the vice chief staff of the Air Force, and three of the militarys top legal officials.Can Trump do this? Yes. The president is the commander in chief and has the authority to pick leadership. Caine will require Senate confirmation to the new position. Legally, only four-star generals are eligible for the position, and Caine is a three-star, but the president has the legal right to waive that requirement in certain circumstances.Why did Trump make the personnel changes? Brown had counted diversity, equity, and inclusion efforts as critical to the militarys ability to function, whereas Trump and new Defense Secretary Pete Hegseth have criticized such efforts as a distraction.Hegseth said on Fox News on Sunday that he wanted legal officials who give sound constitutional advice and dont exist to attempt to be roadblocks to anything anything that happens in their spots. He also said the current lawyers were chosen by an insider pool and that their replacements would shake up the status quo.Whats the big picture? Trumps first-term chair of the joint chiefs, Gen. Mark Milley, said he feared Trump would deploy US troops domestically in an illegal manner. Were Trump to try that now, senior military leaders would face the choice of carrying out his orders or being roadblocks.After Friday nights firings, Trump has the ability to install a handpicked group of officers to lead the worlds most powerful fighting force. Those people will be tasked with fulfilling their oaths to the Constitution, even if that means going against Trump.And with that, its time to log off ...Did you know that the reason our fingerprints are unique is the same reason that no two leopards have the same pattern of spots and no two zebras have identical stripes? Its all related to something called a Turing pattern. This was all new to me, and I learned it from this fascinating video from my colleague Coleman Lowndes. Hope you enjoy it. See you back here tomorrow.See More:
