The latest batch of documents published by WikiLeaks appears to show Hillary Clinton’s campaign communications director joking with a confidant about Catholics and evangelicals in emails sent to John Podesta, chairman of Clinton’s campaign.

Clinton campaign communications director Jennifer Palmieri, who ran communications for the liberal think tank Center for American Progress that Podesta founded, responded to emails from think tank fellow John Halpin, who noted a 2011 report in the New Yorker about News Corp chief executive Rupert Murdoch and Wall Street Journal managing editor Robert Thomson raising their children Catholic.

“Many of the most powerful elements of the conservative movement are all Catholic (many converts) from the [Supreme Court] and think tanks to the media and social groups,” Halpin wrote in the 2011 email, according to WikiLeaks. “It’s an amazing bastardization of the faith. They must be attracted to the systematic thought and severely backwards gender relations and must be totally unaware of Christian democracy.”

Palmieri responded that she believes Murdoch, Thomson and many other conservatives are Catholic because they think it’s “the most socially acceptable politically conservative religion.” “Their rich friends wouldn’t understand if they became evangelicals,” she wrote. Podesta did not respond in the email thread.

The Washington Post reported earlier this year that Russian government hackers penetrated the computer network of the Democratic National Committee, gaining access to an entire database of opposition research.

Podesta, a longtime Clinton family confidant and aide who is reportedly Catholic, said Tuesday that he was told by FBI officials that the intrusion into his email is now part of a wider inquiry into potential Russian cyberattacks. He would not confirm the authenticity of emails released in recent days by the anti-secrecy website WikiLeaks that appear to be from his Gmail account.

The Clinton campaign declined to comment Wednesday on the contents of the 2011 emails in question, instead linking to a tweet from Clinton’s press secretary Brian Fallon.

“Latest faux controversy out of @Wikileaks hack: Accusing Jen Palmieri, who is Catholic, of being anti-Catholic.”

Trump’s running mate Indiana Gov. Mike Pence decried the emails in remarks at Liberty University on Wednesday morning. He said that Clinton should denounce the “bigoted remarks” and apologize to people of faith. Trump also noted the emails while he campaigned in Florida, saying it showed Clinton aides attacked Catholics and evangelicals viciously.

Another email that was released appears to suggest that Clinton’s campaign set up Catholic groups to organize on issues such as contraception. Sandy Newman, president of Voices for Progress, wrote in an 2011 email to Podesta that there needs to be “a Catholic Spring,” referring to the “Arab Spring,” a wave of demonstrations and protests in the Arab world.

“There needs to be a Catholic Spring, in which Catholics themselves demand the end of a middle ages dictatorship and the beginning of a little democracy and respect for gender equality in the Catholic church,” Newman wrote.

“Is contraceptive coverage [in health care] an issue around which that could happen,” he asked.

He noted the controversy with the bishops opposing contraceptive coverage, citing claims that 98 percent of Catholic women have used contraception (that percentage has been questioned, however).

“Of course, this idea may just reveal my total lack of understanding of the Catholic church, the economic power it can bring to bear against nuns and priests who count on it for their maintenance, etc.,” he wrote. “Even if the idea isn’t crazy, I don’t qualify to be involved and I have not thought at all about how one would ‘plant the seeds of the revolution,’ or who would plant them.”

Podesta responded that the campaign had created the groups Catholics in Alliance for the Common Good and Catholics United “to organize for a moment like this.” Leaders from those two groups did not immediately respond to a request for comment Wednesday.

“Like most Spring movements, I think this one will have to be bottom up,” Podesta wrote.

Raymond Arroyo, lead anchor and managing editor of EWTN, the global Catholic network, said the emails have the potential to tip the balance for people who were still undecided. “If you have people on the fences, it is irritating,” Arroyo said.

Arroyo said that the emails describing the “Catholic Spring” will especially rub Catholics the wrong way.

“It makes it seem like you’re creating organizations to change the core beliefs of the church,” he said. “For someone to come and say, ‘I have a political organization to change your church to complete my political agenda or advance my agenda,’ I don’t know how anybody could embrace that.”

Earlier in the summer, internal Democratic National Committee emails were published publicly that appeared to show officials discussing using Sen. Bernie Sanders’s faith against him with voters, with one saying “my Southern Baptist peeps would draw a big difference between a Jew and an atheist.” Those emails were also published by WikiLeaks.

Past polls have suggested Trump could have a problem among Catholics, many of whom have shifted from voting Republican to Democrat this election cycle. While they once voted primarily with the Democratic Party, they have become divided in recent years, with many voting Republican because of issues such as abortion and same-sex marriage. This time around, they are an important swing vote in such states as Florida, Pennsylvania and North Carolina.
