I had forgotten a lot about this except the ending.....
"(a story)... about an arch-conservative congressman, Larry McDonald, who became a leader of the New Right, founded his own private intelligence agency and died at the hands of his geopolitical nemesis, all while in office. McDonald was a militant cold warrior and talented zealot who built his own mini-deep state—a foundation that worked with government and law enforcement officials to collect and disseminate information about supposed subversives.
The tale of Representative Larry McDonald might be the weirdest, most unbelievable one in modern American politics that you’ve never heard."
