Steve Bannon, Donald Trump's new campaign CEO, previously accused Catholics of supporting Hispanic immigration to prop up the church's numbers on his radio program in the spring. 

"I understand why Catholics want as many Hispanics in this country as possible, because the church is dying in this country, right? If it was not for the Hispanics," Bannon told Robert P. George, a Princeton law professor who, along with dozens of other leaders, wrote an open letter to fellow Catholics denouncing Trump. 

"I get that, right? But I think that is the subtext of part of the letter, and I think that is the subtext of a lot of the political direction of this."
