This is a new story, but it was told years ago in The Secret Life of Bill Clinton by Andrews Evan-Pritchet. I’ve read since, that Clinton got $200,000 per load dropped off in Mena. GHWB got much more.
It's not just whispers and rumors anymore.
I read The Secret Life of Bill Clinton years ago. Excellent book. Shocking what the Clintons got away with in Arkansas.
