Steve Mnuchin slammed for trying to zing Axl Rose on Twitter: 'You mad, bro?'

On Wednesday, Treasury Secretary Steve Mnuchin let himself get drawn into a Twitter fight with Guns N' Roses frontman Axl Rose, who called him "officially an asshole." Mnuchin replied "What have you done for America lately?"

Mnuchin was swiftly deluged in mockery from commenters on social media. Some of them made fun of Mnuchin for accidentally using the Liberian flag emoji instead of the American flag and having to redo the tweet.
