Guns N' Roses bassist Duff McKagan described singer Axl Rose as a “super-smart guy” in a new interview with Rolling Stone, saying that the Guns frontman is “concerned about his country.”

McKagan made his remarks with regards to Rose's support of a number of left-wing causes on Twitter, where the singer has also repeatedly criticized Donald Trump and his policies.

McKagan said about Rose, “If he says something on Twitter, he's thought about it. He knows the backup stories from every angle, and if somebody chose to debate him, I don't care who it is, you're going to be f**ked. He's a well-spoken and well-read dude who has experienced a lot. I believe he's concerned about his country.”

McKagan added, “One thing about Axl is if you're going to try to compete with him intellectually, you've lost, because he's a super-smart guy. He's a super-sensitive dude who does his studies.”

McKagan is hitting the road in support of his new solo album, Tenderness, a more subdued affair than he is known for with Guns N' Roses. The latter band will return to the road this fall and may also enter the studio to record its first new album in 11 years.
