Donald Trump's former adviser says Trump posed as his own publicist

Roger Stone, a political strategist and former campaign adviser to

Donald Trump, says Trump posed as his own publicist at least once back in 1991.

Speaking with Breitbart radio on Saturday, Stone said, "This is ridiculous. ... Trump wanted to get his spin and his side of the story, so he handled the press call himself, probably because he didn't want to pay a public relations expert. What difference does it make??"

Last week, The Washington Post reported Trump posed as his own publicist under the name John Miller for decades to plant stories about himself and answer reporters' questions.

Shortly afterward, Trump denied the Post's report, saying, "It was not me on the phone, and it doesn't sound like me on the phone, I will tell you that."

But despite Trump's comments, Stone says it was definitely the real-estate mogul on a press call more than 20 years ago and that the fake name isn't odd behavior. Stone pointed to the Founding Fathers who wrote under pseudonyms.

"This is ridiculous. James Madison, John Adams, Alexander Hamilton — they all wrote under pseudonyms. They all had things they wanted to say, and they wrote under pseudonyms," Stone said.

Stone also criticized the media for discussing whether the GOP front-runner routinely lied to reporters about his identity, saying there are more important issues to discuss.
