Bruce Springsteen and longtime collaborator Joe Grushecky (frontman of Houserockers) have reportedly teamed up for an anti-Trump song dubbed “That’s What Makes Us Great.”

The song premiered this morning on SiriusXM and Grushecky spoke to the Pittsburgh Post-Gazette about the content of the song and teaming with Springsteen. “I sent it to him and he liked it,” Grushecky said of Springsteen’s involvement.

On Trump, Grushecky said that he “lost me the moment he started making fun of special needs people. How could a person like that be President of the United States?”

The song is available for purchase on his website.
