Are pro-Trump commenters legally bound to say nice things about Trump?

Some of the people you see talking on TV or who are quoted in articles about President Trump are legally obligated to say nice things about him.

Trump acknowledged last month that Manigault Newman — author of “Unhinged,” a tell-all book about her time in the White House — had signed a nondisclosure agreement (NDA) when she went to work for his 2016 campaign. He suggested she had violated the agreement, which obligates signers not to disparage Trump or members of his family.

Which raises a question: Are others who have signed an NDA with Trump really being honest in those media interviews, or are they just lauding the president because they legally can’t do otherwise?

.. White House press secretary Sarah Huckabee Sanders hasn’t specified who or how many people have signed, but she has characterized the agreements as “common” and “very normal” for this White House.

.. “I don’t see any acceptable situation where someone has an NDA and doesn’t disclose that in an interview,” he said. “This is material information that goes to the credibility of an interview. The audience has a right to know if the person they’re hearing from has agreed to limit or censor themselves in some way.”

.. Kahn compared undisclosed NDAs to other kinds of would-be conflicts of interest, such as a source with an undisclosed personal relationship or a hidden financial stake in a company he or she was touting to the news media. “It’s completely inappropriate,” he said.
