Republican Sen. Rand Paul of Kentucky strongly objected after Vice President JD Vance asserted in a Saturday post on X that "Killing cartel members who poison our fellow citizens is the highest and best use of our military." "JD ‘I don’t give a s[---]’ Vance says killing people he accuses of a crime is the ‘highest and best use of the military.’ Did he ever read To Kill a Mockingbird? Did he ever wonder what might happen if the accused were immediately executed without trial or representation??" Senator Paul wrote.
