Yes. The Court specifically rejected DOJ's assertion that Cohen could not talk about his book or publish it. I could see a remote interview on CNN, MSNBC, and the networks.
I still expect Trump to sue personally to stop the book from coming out, on the theory that it is all attorney-client privileged material and therefore should not come out. Cohen is smart to get some of this stuff out there before Trump tries to get a gag order. You cannot enjoin a completed act. And if Cohen has not already been disbarred, his felony certainly would cause him to lose his license anyway.
