WASHINGTON – President Donald Trump warned Saturday that longtime aide Madeleine Westerhout has a "fully enforceable confidentiality agreement" – but then added that he doesn't think invoking it will be necessary.

Westerhout, a longtime gatekeeper and personal assistant to the president, abruptly resigned this week after making what Trump described as "hurtful" remarks about his children during an off the record session with reporters.

"While Madeleine Westerhout has a fully enforceable confidentiality agreement, she is a very good person and I don’t think there would ever be reason to use it," Trump said during a storm of tweets on Saturday morning.

The president, who traveled to Camp David on Friday night and then to his Virginia golf club on Saturday morning, then lit into another White House staff member who left acrimoniously: Omarosa Manigault Newman. Manigault Newman left the White House in 2017 and wrote a tell-all book about her experiences with Trump.

"Yes, I am currently suing various people for violating their confidentiality agreements," Trump posted Saturday. "Disgusting and foul mouthed Omarosa is one. I gave her every break, despite the fact that she was despised by everyone, and she went for some cheap money from a book. Numerous others also!"

Trump has frequently relied on non-disclosure agreements for his employees, but experts have questioned their legality when it comes to White House aides.

Trump said that Westerhout called him on Friday yesterday to apologize.

"She...had a bad night," Trump wrote. "I fully understood and forgave her!"

Westerhout’s departure drew significant media attention because of her close relationship with the president. She was among the first staffers who joined Trump in the White House in 2017.

Trump called her comments “a little bit hurtful.”

Trump denied reports that Westerhout had relayed critical remarks Trump made about his children to reporters – specifically Tiffany Trump. The president said he intended to speak with his youngest daughter from Camp David.

“I love Tiffany,” he said.
