'He's dead': Ex-Tea Party congressman loses it at Trump over 'devastating' DACA deal

Former Tea Party U.S. Rep. Joe Walsh (R-IL) went ballistic during an MSNBC interview on Thursday after learning that President Donald Trump may have cut a deal with Democrats over the Deferred Action for Childhood Arrivals (DACA) program that doesn't include money to build a border wall with Mexico.

Mediaite.com reported Walsh called the news "devastating."

"This is a betrayal," Walsh said. "Look, this issue is different. Republican voters will not line up lock, stock and barrel behind President Trump. This issue got Trump elected, period. No amnesty. Build the damn wall!”

“This was the essence of his campaign,” Walsh continued. “If he betrays that promise, he’s dead. He is dead amongst his base, millions and millions of voters will abandon him.”

"He ran on this issue," he fumed. "If he goes back on this, I think he's through. Millions and millions will walk from him."
