White House chief of staff John Kelly hinted Tuesday that President Trump could redact some of the information in a classified memo written by Democrats on U.S. surveillance of Trump’s campaign.

“This is not as clean a memo as the first one,” Kelly told reporters after a meeting on Capitol Hill. “This is a different memo than the first one, it’s lengthier … But again, where the first one was very clean relative to sources and methods, my initial cut is this one is a lot less clean.”
