He’s called The Boss for a reason.

In a new collaboration with Pittsburgh-based rock artist Joe Grushecky, Bruce Springsteen tears into President Donald Trump , according to Yahoo! News . The rock star and Grushecky released the protest song, “That’s What Makes Us Great,” Wednesday on SiriusXM .

Halfway through the song, Springsteen sings , “Don’t tell me a lie / And sell it as a fact / I’ve been down that road before / And I ain’t going back.” He then makes a very clear reference to The Donald singing, “Don't you brag to me that you never read a book / I never put my faith in a conman and his crooks."

The pair then comes together to sing a chorus that serves as a rally cry to defeat Trump .

"It's up to me and you / Love can conquer hate / I know this to be true / That's what makes us great."

This isn’t the first time Springsteen and Grushecky have joined forces. The pair has been friends since the mid-1980s and have collaborated on numerous songs over the years.

Grushecky told the Pittsburgh Post-Gazette he wrote the song around Trump’s inauguration, then told Springsteen about his new tune.

“I had this song, and Bruce and I had been talking. I sent it to him and he liked it. I said, ‘What do you think about singing on it?’ He gave it the Bruce treatment.”

“That’s What Makes Us Great” is available now for purchase on Grushecky’s website and will be on iTunes and streaming services soon.
