WASHINGTON (Reuters) - Whistle-blowing website WikiLeaks is endangering the lives of U.S. forces and people who support the United States around the world, the top U.S. military officer said, ahead of the expected release of more classified U.S. documents.

“I would hope that those who are responsible for this would, at some point in time, think about the responsibility that they have for lives that they’re exposing and the potential that’s there and stop leaking this information,” Admiral Mike Mullen, chairman of the U.S. military’s Joint Chiefs of Staff, said in an interview with CNN’s Fareed Zakaria GPS due to air Sunday.

CNN provided an advanced transcript Friday.
