"First of all, I am not an atheist," Sanders said on CNN’s “State of the Union.”

The emails showed top party officials tried to undermine Sanders’s presidential campaign. In one, an official suggests sending a surrogate to ask an unnamed candidate whether that candidate believed in God.

DNC Chief Financial Officer Brad Marshall’s email does not name the Vermont senator, but it talks about a man of “Jewish heritage” Marshall believes to be an atheist.

"I mean, it is an outrage and sad that you would have people in important positions in the DNC trying to undermine my campaign," Sanders said on Sunday. "It goes without saying the function of the DNC is to represent all of the candidates, to be fair and even-minded."

Sanders said on CNN that the emails were “outrageous” but added they did not come as a “great shock” to him.
