WikiLeaks is a foe and can't be embraced for partisan reasons, the head of an influential conservative group stated Sunday in the wake of the group's disclosure of CIA hacking methods.

"WikiLeaks is an enemy of the United States," said Heritage Action for America CEO Michael Needham, speaking on "Fox News Sunday."

"Both sides need to recognize it cannot be embraced for partisan domestic politics," Needham said of the group.

Some on the right, including President Trump, applauded WikiLeaks for its publication of emails from Hillary Clinton's top campaign adviser. In the past, Needham noted, people on the left backed WikiLeaks when it released damaging disclosures about the Bush administration.

"We have a big problem in this country if there's somebody inside the CIA leaking this kind of information," Needham said. "It's something that we all as Americans need to be deeply concerned about."

Last week, WikiLeaks released stolen documents with information about the CIA's cyber spying methods.

That, said commentator Juan Williams, is far different from past WikiLeaks publications, which shed light on legally dubious domestic spying.

"What was revealed this week was about CIA methods, sources, tactics — overseas," Williams noted.
