It's true.
“Cruz Disagrees With Trump on Muslim Registryâ€
"I'm a big fan of Donald Trump's, but not a fan of government registries of American citizens," Cruz told reporters before a town hall at Briar Cliff University. The "First Amendment protects religious liberty."
Cruz did not disparaging Trump.
He doesn’t support registry. He had no criticism of Trump and specifically refused to attack Trump. Read Cruz’s actual words in post #38, not the media spin about his words.
It’s a matter of semantics, I guess. He is not criticizing Trump. He is criticizing govt. registries of US citizens. And Trump never said anything about those. The reporter did.
