Julián Castro: Presidential candidates should be required to release tax returns

Former Housing and Urban Development Secretary Julián Castro, who is running for president, said at a CNN town hall Thursday that he believes presidential candidates should be required to release their tax returns. 

“I support making it a requirement by statute, Congress passing a law that requires people who are running for president to submit 10 years of their tax returns,” he said.

Castro added that he would release 10 years of his own tax returns “during the next few weeks.”

“It is astonishing that this president still has not released his taxes,” Castro said. “It’s clear that he has something to hide, I don’t.”

But Castro stopped short of saying that it should be a constitutional amendment.
