Donald Trump actually said...

"Nobody really knows, nobody really knows for sure."

"He did nothing about it. Why did he do nothing about it? He was told it was Russia by the CIA, as I understand it."

"I think it was Russia, and I think it could have been other people, in other countries. It could have been a lot of people interfered."

"I think it was Russia but I think it was probably other people and/or countries and I see nothing wrong with that statement."
