Grushecky told the Post Gazette that he penned the tune back in January, when Trump took office.
He then sent it to his old pal, Springsteen.
"I said, 'What do you think about singing on it?'" Grushecky said. "He gave it the Bruce treatment."
Grushecky was inspired to write the song after Trump mocked a reporter's disability.
[Trump] lost me the moment he started making fun of special needs people. How could a person like that be president of the United States? Regardless of all the other [stuff], that to me is appalling. I have special needs people in my family and in my neighborhood. I worked with special needs people my whole life, and I was really offended by it.
Trump's immigration stance makes an appearance in the song, with lyrics like: "Some wanna slam the door / Instead of opening the gate / Aw, let’s turn this thing around / Before it gets too late."
Springsteen also sings, "Don’t tell me a lie / And sell it as a fact / I’ve been down that road before / And I ain’t goin’ back / And don’t you brag to me / That you never read a book / I never put my faith / In a con man and his crooks."
Sounds about right.
The song is now available on Gushecky's website, iTunes, and streaming services.
