In an interview with The Washington Post aboard his tour bus, Willie Nelson urged Americans to bridge what he calls a great divide in politics. 

The 84-year-old also asks Attorney General Jeff Sessions to open his mind on drug policy. 

Nelson, a marijuana advocate and purveyor, strongly disagrees with Sessions’s statement in March that marijuana dependency is “only slightly less awful” than heroin dependency.

Nelson said Sessions should “try heroin and try marijuana and then call me and let me know if he still thinks it's the same thing and one is as bad as the other.”

Watch the interview, which taped before Nelson's show at Merriweather Post Pavilion on July 14, above, to hear more from Nelson on politics — and a musical riff on The Washington Post slogan “Democracy Dies in Darkness.”
