New York (CNN Business) A former Trump Organization executive says she thinks President Donald Trump may resign rather than face possible removal from office by impeachment.

"He does a lot of things to save face," Barbara Res , a former Trump Organization vice president, told CNN's Brian Stelter on Reliable Sources Sunday.

"It would be very, very, very bad for him to be impeached," Res said. "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 said she was hesitant to share her opinion, because "I could very well be wrong."

But Res has first-hand experience working with Trump. She was the construction engineer on some of his key projects, including Trump Tower, and she is the author of "All Alone on the 68th Floor: How One Woman Changed the Face of Construction," which partly chronicles her time working for the President while he ran his company.
