Over 700 former national security and military officials endorsed Kamala Harris for president in an open letter, published Sunday. The letter described the 2024 election as a choice between “serious leadership and vengeful impulsiveness,” criticizing Donald Trump as “impulsive and ill-informed.” Signatories included retired four-star generals, former Cabinet-level officials, and three Trump-era officials. The letter accused Trump of undermining the peaceful power transfer and criticized his treatment of U.S. allies.
