Think it's rather obvious Trump thinks his biggest mistake was listening to anyone who told him "no" during his
presidency.
Specifically, Trump has talked about bringing back death by firing squad, by hanging, and, according to two of the sources, possibly even by guillotine. He has also, sources say, discussed group executions. Trump has floated these ideas while discussing planned campaign rhetoric and policy desires, as well as his disdain for President Biden’s approach to crime.
Though every other Republican agrees.
