Trump’s big immigration speech in Arizona went over like a lead balloon with Hispanics — even the ones who have pledged their support to them.

GOP analyst Leslie Sanchez reports that a “Hispanic leader who advises Trump camp [is] telling me half of Trump’s Hispanic advisory board is ready to resign today.”

If you’re keeping track at home, that means 15 out of 30 members of the Trump National Hispanic Advisory Council are threatening to bolt after Trump reiterated his hardline stances on immigration on Wednesday.

In followup tweets, Sanchez explains that these board members feel as though Trump misled them on his intentions on dealing with undocumented immigrants — and it sounds like they’re furious about it.

They feel misled. Really "hot" crowd. Extremely upset. https://t.co/lS3EcLki5d

I'm told greatest issue of contention is the false belief that "self deportation" is a viable option. Don't believe it's humane or real #2

Sanchez, who headed up the White House Initiative on Educational Excellence for Hispanic Americans under President George W. Bush, is very well connected to Hispanic Republican bigwigs.

Earlier today, we learned that National Hispanic Advisory Council member Jacob Monty had stepped down from his position on the board, and now it seems like several others are ready to follow in his footsteps.

“I was a strong supporter of Donald Trump when I believed he was going to address the immigration problem realistically and compassionately,” he told Politico. “What I heard today was not realistic and not compassionate.”

Additionally, top Latino Trump supporter Alfoso Aguilar officially renounced his support for the candidate on CNN on Thursday, and insisted that he wasn’t the only Hispanic Trump fan out there who changed his mind after watching Trump’s Arizona speech.
