Is that really her trade? And if it is, she still decides who to do business with. She is a veteran lawyer, and if she maintained a law practice she could contend that she is entitled, actually obligated, to provide a vigorous defense to anyone who hires her. But she gets to choose her clients, and if they included arms dealers, foreign tyrants and drug kingpins, we would be entitled to question her integrity and her judgment. As a corporate speaker, she doesn't have to take big money to from entities that she might later be called on to regulate, even prosecute, or she could take the money and donate it to, say, non-profit legal clinics that help families fight bank foreclosures. But that's not what she's been doing. And it's a little misleading to call her a "private citizen" in the usual sense; she doesn't have a government job currently, but she's been running for President pretty much since the day Bill left the White House, and everybody knew that she'd run in 2016. She gets paid for future access.Why is this a problem ? I understand that there could have been a problem if she was still Secretary of State but as an ex-SoS she was entitled to ply her trade as a corporate speaker.

Depending on the contract that she had with her clients, the intellectual property for that speech may be hers, theirs or a combination of the two. There may even be a confidentiality clause in her contract.
Do you think she couldn't insist on a contract that provides whatever she wants? If there is a confidentiality clause, she put it there.
