Exclusive: Former Mar-a-Lago employee-turned-witness repeatedly contacted by Trump and associates...

Three months after the FBI seized classified records from Mar-a-Lago last August, a longtime employee of Donald Trump’s private club quit his job.

Within days, the former president did something he rarely did – Trump called the former employee on his cell phone to ask why he was leaving after two decades of working at the resort, according to two sources and material seen by CNN.

The employee told the former president he had another business opportunity he wanted to pursue. The message later got back to the former employee that Trump thought he was a “good man.”

But he wasn’t just any staffer at the club – the former employee was a witness to several episodes special counsel Jack Smith included in his federal criminal indictment charging the former president with mishandling classified documents.

He had moved several boxes for Trump and was also privy to conversations referenced in the indictment between Trump and his two co-defendants, Mar-a-Lago property manager Carlos De Oliveira, and Trump’s body man Walt Nauta – putting the former employee in a unique group of Mar-a-Lago staffers who could be in a position to provide valuable information to investigators.
