SLASH

Welcome (back) to the jungle.

Slash and Axl Rose of Guns N' Roses perform onstage in Madison Square Garden last October. Treasury Secretary Steven Mnuchin challenged hard rock musician and Guns N' Roses member Axl Rose on Twitter Wednesday evening. The Treasury secretary, who oversees the debt issuance and fiscal wellbeing of the United States, quipped to Rose: "What have you done for the country lately?" Mnuchin, who is also one of President Donald Trump's chief economic advisors, tweeted in response to Rose. It was unclear what may have provoked Rose's original tweet that disparaged the Treasury secretary.

In this week’s edition of “Sounds of the Toyota Green Room,” rocker Slash talks with “CBS This Morning” co-host Gayle King about performing in front of a live audience. The New Yorker’s Nicholas Thompson talks with Gayle about Periscope and the Floyd Mayweather-Manny Pacquiao fight.
