“As a private citizen, former or retired service members are free to speak with the media and exercise their First Amendment rights,” Derrick-Frost told Business Insider. ”However, it is important for all former service members to adhere to their signed non-disclosure agreements (NDAs) when they seek to openly discuss classified or sensitive information, or make claims about their active duty operations or accomplishments.

“NDAs are voluntarily executed by service members. After a thorough briefing on the NDA and what each paragraph contains, the service member is aware that his/her signature signifies their understanding and intent to comply with the lifelong obligation for protecting National Defense Information.”

Derrick-Frost went on to remind the “individual” involved in the Fox News documentary that he would still be “bound” by this NDA.
