Joe Scarborough Debuts Satirical Music Video Mocking Donald Trump

The song pokes fun at Trump for "going soft" in more ways than one.

"He's softening — Is there a pill for that?"

"He's waffling — His courage just went splat!"

So croons Morning Joe host Joe Scarborough in a satirical country-western music video aimed at Donald Trump's newly qualified stance on immigration that was posted to Scarborough's Facebook page Wednesday afternoon.

In the song, Scarborough lights into the Republican presidential nominee, referring to him as "Amnesty Don," a "soft and flaccid man" who "said he'd build a wall for us, but then he up and ran."

The morning host, who moonlights as an occasional rock musician, dons a down-home western accent for his performance, adopting the persona one of the let-down "cowboys" who've smelled the "dirty con of Amnesty Don."

The song comes as Republican presidential candidate Donald Trump makes a surprise visit to Mexico to meet with Mexican president Enrique Peña Nieto, who once compared Trump to Adolf Hitler.

A hallmark of Trump's campaign rhetoric has been his hard-line stance on immigration. His promise to build a wall between Mexico and the U.S. — and to have "Mexico pay for it" — has been a source of national and international controversy.

Trump and Scarborough, who were once quite chummy, started spatting in February after Trump failed to disavow an endorsement from a leader of the Ku Klux Klan, prompting Scarborough to "disqualify" his candidacy. The conflict has escalated from there.

"Joe Scarborough initially endorsed Jeb Bush and Jeb crashed, then John Kasich and that didn't work," Trump said in a May tweet. "Not much power or insight!"

The Trump campaign has yet to respond to Scarborough's musical number.
