Another of president Donald Trump's former confidants, Barbara Res, is predicting the scandal-ridden businessman will resign rather than face the humiliation of impeachment.

Trump will resign to "save face," claims Res, a professional architect who worked for Trump for a decade starting in 1980. She rose from being vice president to executive vice president in charge of construction at the Trump Organization.

In this key role, Res worked closely with Trump when he was building his real estate empire. She also authored the book, “All Alone on the 68th Floor: How One Woman Changed the Face of Construction.”

"He does a lot of things to save face," said Res told CNN's Brian Stelter, Sunday.

"It would be very, very, very bad for him to be impeached," she pointed out.

"I don't know that he'll be found guilty but I don't know that he wants to be impeached. I think that's what this panic is about. And my gut (instinct) is that he'll leave office, he'll resign. Or make some kind of a deal, even, depending on what comes out."

Res has been critical of Trump over the past few years, and recently said Trump's behavior has gotten worse.

"This is Trump -- I say Trump Squared because he's had, since I knew him, many, many years of fame and fortune and getting richer and now he actually does believe he's a stable genius and he does believe he could shoot somebody on Fifth Avenue, and so far it looks like he can," she said.

Res said she agrees with George Conway, husband of Trump adviser Kellyanne Conway, that Trump is completely unfit to hold the office of the president of the United States. Her belief isn't "necessarily for the mental reasons that you talk about but because he didn't have the experience, you know, lots of different things."

As for Trump's unhinged reactions and the massive number of Twitter rants to the growing Ukraine scandal, Res said Trump's reactions are still vintage Trump.

"He was always very quick to react, he never responded to anything, always reacted to it and got very, very angry," noted Res.

In September, Res revealed how Trump slammed blind people and wanted them banned from his swanky Trump Towers by making it impossible for them to ride the elevators.

Res said Trump ordered architects to remove the braille floor numbers from the panels at the elevators even if it meant breaking the law.

“What’s this?” Trump asked the architect.

“Braille,” he replied. Trump then told the architect to get rid of the Braille.

“We can’t,” protested the architect. “It’s the law.”

“Get rid of the (expletive) braille. No blind people are going to live in Trump Tower. Just do it,” yelled Trump.

In August 2018, another Trump confidant, Tony Schwartz, predicted Trump will resign rather than face impeachment. Schwartz wrote "The Art of the Deal," the book that launched Trump on his road to the presidency.

"Trump will resign as I always assumed. Only matter of time now,” said Schwartz in response to the scandals battering Trump at the time.
